Comprehensive Illinois Rules of the Road and Driver Safety Study Guide
Required Use and Operation of Headlights
In the State of Illinois, driver requirements for headlight usage are specific to visibility and environmental conditions. Headlights must be activated from dusk until dawn. Additionally, they are required during any periods of poor visibility and specifically whenever weather conditions necessitate the use of windshield wipers. When operating a vehicle with high-beam or bright lights, drivers must dim them at least feet before meeting an oncoming vehicle and at least feet before overtaking another vehicle from behind.
While driving in foggy conditions, it is mandatory to use low-beam headlights rather than high-beams to maintain visibility. Drivers should maintain a speed that ensures they can come to a complete stop within their specific field of vision. It is noted that flashing lights routinely or keeping a foot on the brake pedal to illuminate taillights specifically for fog visibility are not recommended actions or requirements.
Driving Under the Influence of Alcohol and Drugs
A driver's license will be suspended in Illinois if, following an arrest for Driving Under the Influence (DUI) of alcohol or drugs, the individual takes a chemical test (consisting of breath, blood, or urine) and registers an alcohol concentration equal to or over the legal intoxication level of . Suspension also occurs if the chemical test reveals any trace of a controlled substance or cannabis (marijuana). Refusing to submit to these chemical tests also results in an automatic suspension. Specifically, a first offense for refusing a chemical test results in a -month license suspension, while a second or subsequent refusal within a -year period results in a suspension of months. Such a refusal can also be used as evidence in court proceedings for a DUI charge.
Driving privileges will be fully revoked if a driver is convicted of driving or being in actual physical control of a vehicle while under the influence of alcohol, other drugs (including impairing prescription medications), or a combination thereof. To reinstate full driving privileges after a DUI revocation, an individual must wait a minimum of year, submit to a professional assessment of their drug and alcohol use, and attend a remedial or rehabilitation program. Furthermore, the person must be approved for reinstatement by the Secretary of State's Office of Administrative Hearings, pay a reinstatement fee, and carry high-risk auto insurance for a duration of years.
Rules of the Road for Intersections and Turning
Intersections are high-risk areas, and many accidents occur because drivers fail to slow down and look carefully to the left and right before entering. When waiting at an intersection where the traffic signal turns green, a driver may only proceed after first yielding the right-of-way to any persons or vehicles already within the intersection. If a signal shows both a red light and a green arrow in the intended direction of travel, the driver may proceed in the direction of the arrow with caution. A flashing red traffic signal is legally equivalent to a stop sign, requiring a full stop.
When a right turn against a red signal light is permitted, the driver must first come to a complete stop and yield the right-of-way to all pedestrians and vehicles in the intersection before cautiously making the turn. When making any turn in a business or residential district, a continuous turn signal must be given for at least feet prior to the turn. When approaching a stop sign, the vehicle must be stopped at a marked stop line. If no line exists, the driver must stop before entering the crosswalk or, if there is no crosswalk, before entering the intersection itself.
Right-of-Way and Interaction with Special Vehicles
Drivers must yield the right-of-way to any authorized vehicle engaged in highway construction or maintenance that is displaying amber (yellow) oscillating, rotating, or flashing lights. When an authorized emergency vehicle using a siren and flashing lights approaches, the driver must pull over to the right-hand edge of the highway and stop if possible.
School bus safety is strictly enforced; passing a school bus while it is receiving or discharging passengers can result in a license suspension of at least months. On a two-lane highway, drivers must stop before meeting or overtaking a school bus that has its red warning lights flashing and stop signal arm extended. On a roadway with four or more lanes, a driver does not need to stop if they are traveling in the opposite direction of the bus, provided at least lanes of traffic travel in that opposite direction, though they should still proceed with caution.
Motorcycles and Other Road Users
Motorcycles are entitled to the same right-of-way privileges as other motor vehicles and are permitted to use the full width of a traffic lane. When passing a motorcycle, a driver should not attempt to share the lane; instead, they must change lanes and pass in the same manner they would pass any other vehicle. Special attention should be given to motorcyclists at intersections, railroad crossings, bridges, and during inclement weather.
Pedestrians and other vehicles must also be prioritized when a driver is moving out of an alley, private road, or driveway within an urban area; the driver must stop before reaching the sidewalk and yield to all sidewalk and roadway traffic before proceeding. Furthermore, it is strictly unlawful for a person to travel across private property, such as a gas station or parking lot, specifically to avoid an official traffic control device.
Emergency Procedures and Handling Vehicle Failure
If a vehicle's tire has a blowout, the driver should grip the steering wheel firmly, take their foot off the gas pedal, and allow the vehicle to slow down significantly before driving onto the shoulder; the brakes should not be applied quickly. Similarly, if the front right wheel runs off the pavement, the driver should grasp the steering wheel tightly and take their foot off the accelerator rather than swinging back onto the pavement immediately.
In the event of hydroplaning (skidding on water), the driver should take their foot off the accelerator and let the vehicle slow down naturally. If the rear end of the vehicle starts to skid on a slippery road, the driver should turn the front wheels in the direction of the skid. When driving in winter, motorists must be aware that the road surface of a bridge may be dangerous because ice can form on bridges even when other pavement surfaces remain clear.
Railroad Crossings and Passing
When approaching a railroad grade crossing that lacks a warning system (such as gates or electric flashing lights), a driver must look, listen, slow down, and be prepared to stop, proceeding only when it is safe. If flashing signals are present, a driver must wait for the train to clear and then check to ensure another train is not approaching on a different track before proceeding. When passing another vehicle on any road, the driver should not cut back into the right lane until the passed vehicle is visible in the rearview mirror. It is illegal to pass another vehicle on the shoulder of the road. On a two-lane pavement, a single solid yellow line on the driver's side indicates that they must not cross the line to pass another vehicle.
General Licensing and Resident Requirements
Illinois residents are required to insure their vehicles for liability and must carry proof of this insurance within the vehicle. This proof must be produced when requested by law enforcement during traffic violations, random checks, or following a traffic accident. Drivers must hold a valid license properly classified for the specific type of vehicle they are operating, including borrowed or rented vehicles. It is also prohibited for drivers to wear headsets or have a television receiver visible from the driver's seat while operating a vehicle.
Drivers under the age of who drive after curfew hours must be accompanied by a parent, legal guardian, or an approved person at least years of age. If these conditions are not met, the license is considered invalid during curfew hours. Regarding safety restraints, the driver and all front-seat passengers age and older must wear seat belts. Children under the age of are required by Illinois law to be secured by an appropriate restraining system or seat belt regardless of where they are seated in the vehicle. Finally, it is noted that the most common cause of rear-end collisions is the vehicle in back following too closely.
