The answer

Answer: D. It is illegal to drive if your BAC is .08% or more. You can still be convicted of DUI at a lower BAC if your driving ability is impaired. Alcohol affects your vision and slows your reaction time even below the level of illegal intoxication, so even a small amount increases the chance of a crash.

The answer

Answer: D. At an all-way stop, the first driver to stop is the first to go. If two vehicles arrive at the same time, the one on the left yields to the one on the right. Other drivers must wait their turn, and you may also see 3-WAY, 5-WAY or ALL-WAY panels under the stop sign at such intersections.

The answer

Answer: C. Some parking areas have spaces equipped with charging stations for electric vehicles.

The manual lists this rule alongside the parking rules for persons with disabilities, which also reserve certain spaces for specific vehicles.

The answer

Answer: B. Diamond-shaped signs are warning signs. They may be yellow, yellow-green or orange with black words or symbols, and they warn you about hazards or possible hazards on or near the roadway. When you see one, slow down and use caution, because conditions ahead may require you to change speed or position.

The answer

Answer: C. The foot brake must be strong enough to stop a vehicle traveling 20 mph within 30 feet. The emergency or parking brake must stop the vehicle within 55 feet at the same speed, and it must also be able to hold the vehicle on a grade or hill. Motor-driven cycles need only one brake.

The answer

Answer: D. Unless signs say otherwise, city and town areas have a 30 mph limit in Illinois. The other defaults in the manual are 70 mph on interstates and tollways, 65 mph on four-lane highways, 55 mph on other highways and rural areas, 15 mph in alleys and 20 mph in school zones. Local municipalities may post different limits.

The answer

Answer: B. Cannabis may only be transported in a vehicle in a sealed, odor-proof, child-resistant container. Neither the driver nor any passenger may use cannabis in a motor vehicle. Illinois also bars driving while impaired by cannabis, and driving while impaired or transporting cannabis illegally may cost you your driving privileges.

The answer

Answer: C. At a T intersection with no signs or signals, the driver on the terminating highway must yield to cross traffic, so the driver on the through road goes first. The manual's figure shows the vehicle on the stem of the T giving way. This is one of several right-of-way situations the manual lists for uncontrolled intersections.

The answer

Answer: C. The Rules of the Road says a driver who seeks a basic license to operate a car in Illinois is issued a Class D license. Classes are set by the gross vehicle weight rating of the vehicle you drive, so a normal passenger car falls under the basic class. Motorcycle and commercial privileges follow separate procedures and manuals, so they are not part of the basic car license.

The answer

Answer: C. It is illegal to operate or permit a sound system, radio or player, to be run at a volume that can be heard 75 feet or more from a vehicle being driven on a highway. This keeps drivers able to hear sirens and horns.

The answer

Answer: B. Facing uphill with a curb, turn the front wheels away from the curb. Facing downhill with a curb, turn them toward the curb, and with no curb, turn the wheels toward the side of the road where you are parked. In every case, also put the gear selector in park and set the parking brake if necessary.

The answer

Answer: A. Illinois law prohibits flashing your turn signals as a courtesy or do-pass signal to other drivers. A driver who passes must decide independently whether the pass is safe, check that the left lane is clear of oncoming traffic for enough distance, and return to the right lane only when the whole passed vehicle is visible in the rearview mirror.

The answer

Answer: D. An autocycle is a three-wheeled vehicle that has a steering wheel and seating that does not require the driver to straddle or sit astride it. It may be operated on Illinois roads when it is correctly titled and registered with the Secretary of State, and the operator must hold a valid Illinois driver's license.

The answer

Answer: D. When a green arrow points upward you may go straight ahead only. A green arrow pointing to the right allows a right turn, and one pointing to the left allows a left turn. In every case you should first yield the right of way to traffic and pedestrians already within the intersection or crosswalk.

The answer

Answer: A. Green is the color of guide signs. They tell you where you are, which way to go, and how far it is to upcoming destinations. They also give distances to upcoming destinations, in contrast to the warning signs that describe road conditions and hazards.
