Lake County Adult Driver Education

Online Adult Driver Education in Lake County, Illinois

If you are 18, 19, or 20 and applying for your first Illinois driver's license, you may be required to complete the state's six-hour Adult Driver Education Course before applying for your license. Illinois requires the course when all three conditions apply: you are 18 through 20, you are applying for an Illinois driver's license for the first time, and you have never completed an approved driver education course through a high school or commercial driving school.

Eligible applicants throughout Lake County can complete the classroom portion online through a provider certified by the Illinois Secretary of State. This includes eligible first-time applicants living in communities such as Waukegan, Lake Forest, Highland Park, Zion, Gurnee, Libertyville, Mundelein, and Antioch.

After successfully completing the course and provider-administered final test, you receive access to a Certificate of Completion. You should download and print the certificate, then take it with your required identification documents to an Illinois Secretary of State Driver Services facility. You must still complete the applicable vision, written, and behind-the-wheel road examinations. Completing the six-hour course does not automatically issue an Illinois driver's license or give you permission to drive.

Lake County presents a wide range of driving conditions for new drivers. The county includes dense urban and suburban corridors, Lake Michigan shoreline communities, rural roads, major highways, railroad crossings, commuter routes, and extensive municipal and county road networks. Lake County's official highway map shows the relationships among these routes, municipalities, county highways, state highways, U.S. routes, and the Tri-State Tollway.

Who Must Take Adult Driver Education?

Illinois uses a three-part eligibility test for the six-hour Adult Driver Education requirement.

You generally must complete the course if all three statements are true:

You are 18, 19, or 20 years old.

You are applying for an Illinois driver's license for the first time.

You have never completed any driver education course in high school or through a commercial driving school.

If all three conditions apply, you must successfully complete a six-hour Adult Driver Education Course before obtaining your Illinois driver's license. The course must be provided by a provider certified by the Illinois Secretary of State.

The requirement applies to eligible first-time applicants throughout Lake County. Your community does not change the statewide eligibility rules.

Who Does Not Need This Course?

The six-hour Adult Driver Education Course does not apply to every Illinois licensing situation.

You generally do not need this particular course if:

You are under 18 and are following Illinois' separate teen driver education and Graduated Driver Licensing process.

You are 21 or older, unless another specific licensing requirement applies to your circumstances.

You already have a valid out-of-state driver's license and are moving to Illinois. The Secretary of State states that you must surrender the out-of-state license and complete the applicable Illinois requirements rather than taking the Adult Driver Education Course solely to transfer your license.

You previously completed an approved high school driver education course and can provide acceptable proof of completion.

You previously completed an approved commercial driving school course that satisfies the Illinois requirement.

You have already been licensed in a manner that means you are not a first-time Illinois license applicant.

The Secretary of State specifically states that an applicant who completed high school driver education can apply without taking the Adult Driver Education Course when acceptable proof of completion is provided.

Applicants under 18 follow Illinois' separate Graduated Driver Licensing process.

Illinois Online Course Rules

The Adult Driver Education Course is at least six hours long. Illinois allows certified providers to offer the course in a classroom setting or online, depending on the provider's certification.

Driving in Lake County

Lake County has a particularly varied driving environment. Its transportation system includes state highways, U.S. routes, the Illinois Tollway, county highways, municipal streets, and township roads. The county states that its Division of Transportation maintains more than 300 centerline miles of county arterial and collector roads, while municipalities and townships maintain other portions of the local road system.

For a new driver, this means a trip across Lake County can involve several different types of roads within a short distance.

Urban and suburban traffic

Waukegan, North Chicago, Park City, Lake Forest, Highland Park, Highwood, and other developed communities have more urbanized streets, signalized intersections, commercial areas, pedestrians, and transit activity.

Lake County's transportation planning also recognizes connections between schools, parks, employment centers, commercial areas, and transit stops. New drivers should expect pedestrians and cyclists near these destinations and should avoid treating a wide suburban arterial like a limited-access highway.

Rural and semi-rural roads

The northern and western portions of Lake County include less densely developed areas with two-lane roads, open land, drainage features, and longer distances between major intersections. Drivers may encounter slower agricultural vehicles and should be prepared for vehicles entering or leaving fields and driveways.

Interstate traffic

Interstate 94, the Tri-State Tollway, is the only interstate highway in Lake County, according to the county's official jurisdiction information. It carries regional traffic and connects with numerous major cross streets and interchanges throughout the county.

Railroad crossings

Railroad crossings are an important local consideration. Lake County maintains specific pavement-marking standards for railroad crossings on county highways, including warning signs, crossbuck markings, stop bars, and clearance markings designed to prevent vehicles from stopping on tracks.

The county has also documented road closures and detours associated with railroad crossings. For example, a Lake County detour map for St. Mary's Road shows a road closure at a railroad crossing near the Elgin, Joliet and Eastern Railway.

Winter weather

Winter weather can create snow, ice, reduced visibility, and slippery pavement. Lake County's Division of Transportation plans and budgets for winter ice-control materials, including salt for the winter season.

New drivers should slow down for conditions, increase following distance, brake smoothly, and allow extra travel time.

Flooding and heavy rain

Flooding is another genuine Lake County driving concern. County watershed planning documents have identified roadway flooding in areas such as Fox Lake following intense rainfall. Heavy storms can overwhelm drainage systems and result in rapidly changing road conditions.

Never assume that a road remains safe simply because it was passable a few minutes earlier. Follow posted closures and detours and never drive through water when you cannot determine its depth or the condition of the roadway underneath.

Commuter and transit traffic

Lake County is part of the Chicago metropolitan transportation system and has substantial commuter travel. County transportation studies have documented differences in commute patterns across the county and connections with Metra and Pace.

A new driver should expect heavier traffic during common commuting periods, especially around major arterials, expressway interchanges, and communities with rail stations.

Major Roads and Highways

Lake County's official highway map identifies the county's major transportation corridors and the interchange network associated with I-94.

Interstate 94 and the Tri-State Tollway

I-94 is the only interstate highway in Lake County. It forms a major north-south regional corridor and connects with important cross routes including Illinois Routes 22, 60, 176, 137, 120, 21, 132, and 173, as well as U.S. Route 41 and other major roads.

U.S. Route 41

U.S. Route 41 is a major north-south corridor through Lake County. It connects communities along the eastern portion of the county and provides access to other regional routes. The county's highway map and transportation materials identify U.S. 41 as part of the county's major roadway system.

U.S. Route 45

U.S. Route 45 provides another important north-south connection through western Lake County and intersects major east-west routes.

Illinois Route 12

Illinois Route 12 is an important route through western Lake County and connects communities in the northwest portion of the county with the broader regional roadway system.

Illinois Route 21

Illinois Route 21, also known as Milwaukee Avenue in portions of Lake County, is an important north-south arterial and an I-94 interchange route.

Illinois Route 22

Illinois Route 22, commonly known as Half Day Road in the eastern portion of the county, is an important east-west corridor connecting communities and providing an I-94 interchange.

Illinois Route 60

Illinois Route 60, including Townline Road in portions of the county, provides a major east-west connection across central Lake County and intersects I-94.

Illinois Route 83

Illinois Route 83 is an important north-south roadway serving western and central portions of Lake County.

Illinois Route 120

Illinois Route 120, also known as Belvidere Road in portions of the county, crosses the county and provides an I-94 connection.

Illinois Route 131

Illinois Route 131 provides a north-south connection in the eastern portion of Lake County, including areas around Waukegan and the northern suburbs.

Illinois Route 132

Illinois Route 132, or Grand Avenue, is a major east-west corridor serving Gurnee and surrounding communities. It also connects with the I-94 interchange system.

Illinois Route 137

Illinois Route 137, also known as Buckley Road in portions of the county, crosses central Lake County and connects Libertyville, Green Oaks, Waukegan, and North Chicago. The county has identified the Route 137 corridor for transportation improvements and multimodal connections.

Illinois Route 173

Illinois Route 173 is a significant east-west route across northern Lake County. Lake County has maintained a dedicated Route 173 Corridor Planning Council because of the route's importance to transportation, development, and the I-94 interchange area.

Illinois Route 176

Illinois Route 176 provides an east-west connection through central Lake County and intersects the I-94 corridor near Mundelein and Libertyville-area communities.

Primary Local Driving Topic: Railroad Crossings and Train Traffic

Railroad crossings are an especially useful safety topic for a new Lake County driver because the county's transportation system includes both roadway traffic and rail infrastructure.

Lake County has formal engineering standards for railroad crossings on county highways. Those standards address warning signs, crossbucks, stop bars, pavement markings, and clearance markings. The county also documents locations where railroad crossings have affected roadway operations and required detours.

The county's transportation network also includes Metra commuter rail service. Lake County planning documents identify Metra stations and rail connections in communities including North Chicago, Lake Forest, Round Lake, Mundelein, and other areas.

For a new driver approaching a railroad crossing:

Begin slowing when you see the railroad warning signs.

Look both ways for approaching trains.

Never drive around a lowered crossing gate.

Never stop on the railroad tracks.

Make sure there is enough room on the other side before crossing.

Watch traffic ahead because a line of vehicles can stop unexpectedly after the tracks.

Pay attention to road markings that identify a no-stopping or clearance area.

If a crossing is closed, follow the posted detour instead of attempting to bypass the closure.

This is especially important on unfamiliar roads. A driver who is focused only on the vehicle directly ahead may not recognize a railroad crossing until there is little room to react.

Additional Driving or Safety Topic: Flooding and Wet-Weather Conditions

Lake County's waterways, drainage systems, and low-lying areas can create difficult driving conditions during major rain events.

A county watershed plan documented significant roadway flooding in Fox Lake after intense rainfall in July 2017. The plan noted that flooding occurred rapidly in some areas and that major roads were closed.

For a new driver, the safest response to heavy rain is to slow down and reassess the road ahead.

Practical precautions include:

Reduce speed when visibility decreases.

Increase following distance.

Use headlights when required and when they improve visibility.

Avoid sudden braking and steering.

Watch for standing water.

Follow barricades and official detours.

Never drive around a road-closure barrier.

Do not attempt to cross moving or deep water.

Remember that water can conceal pavement damage or a washed-out roadway.

A route that is normally familiar can become substantially more difficult during a severe storm. New drivers should be willing to postpone a trip when conditions become unsafe.

Take the Course Online Throughout Lake County

Eligible Lake County residents can complete the six-hour Adult Driver Education classroom component online through a provider certified by the Illinois Secretary of State.

The online option can be useful whether you live in Waukegan, Zion, North Chicago, Lake Forest, Highland Park, Gurnee, Libertyville, Mundelein, Antioch, or another Lake County community. The requirement is based on your age and licensing history, not on which Lake County municipality you live in.

The current Illinois Secretary of State certified-provider list identifies IllinoisAdultDriversEd.com as an online Adult Driver Education provider.

Completing the course online does not eliminate the in-person licensing requirements. After successfully completing the course and receiving your Certificate of Completion, you must still visit a Secretary of State Driver Services facility with the certificate and required identification documents and complete the applicable examinations.
