Colorado DMV Exam Simulator

Correct answer: 5 nanograms of THC per milliliter

There is a permissible inference that a driver was DUI if the driver’s blood contained 5 nanograms of THC per milliliter of blood.

Correct answer: 15 years old

The requirements to obtain an instruction permit vary by age, and the youngest a minor can begin is 15 years old (with a required 30-hour driver education course at that age).

Correct answer: On a crosswalk, sidewalk, bridge or railroad tracks

You may not park on a crosswalk, sidewalk, bridge, elevated structure, railroad tracks or any controlled-access highway.

Correct answer: Take your foot off the accelerator and pump the brake pedal several times

For brake failure, take your foot off the accelerator and pump the brake pedal several times to build up pressure. If that fails, use the parking brake slowly and shift to lower gears to slow down.

Correct answer: The driver of a truck, bus, emergency vehicle, or recreational vehicle (a large vehicle)

Before entering a roundabout, Colorado law requires drivers to yield to the driver of a truck, bus, emergency vehicle, or recreational vehicle (large vehicle) when entering, exiting, or driving in the roundabout.

Correct answer: When the snow or ice begins to melt

Streets and highways covered with snow, snowpack or ice are most hazardous when the snow or ice begins to melt, because the surface becomes slick and tires grip even less.

Correct answer: The full width of a lane

Motorcyclists have the same rights and responsibilities as other drivers and are entitled to the full width of a lane. They often move within the lane to see, be seen and avoid hazards.

Correct answer: To let pedestrians cross the road safely, using a yellow-red flashing sequence to alert drivers

HAWK signals are traffic signals that allow pedestrians to cross the road safely. They operate in a yellow-red flashing sequence to alert motorists that pedestrians need to cross.

Correct answer: In poor weather, or near railroad tracks, pedestrians, bicyclists, animals, and school buses

Regardless of the posted limit, it is important to slow down in certain conditions — for example during poor weather, or near railroad tracks, pedestrians, bicyclists, animals, and school buses.

Correct answer: Ahead, to the side, and behind your vehicle

You must check for hazards or vehicles in the lane you want to enter, which means checking for traffic ahead, to the side, and behind your vehicle before you change lanes.

Correct answer: No — there is no THC permissible-inference level for DWAI

The 5-nanogram inference applies only to DUI. There is no THC permissible-inference level for DWAI; most marijuana-impaired drivers are convicted based on behavioral symptoms as well as blood THC levels.

Correct answer: A 30-hour driver education course

A minor who is 15 to 15½ must complete a 30-hour driver education course before getting the instruction permit. (A future law, effective January 1, 2027, will require the 30-hour course for all applicants 15 to 17.)

Correct answer: Within 15 feet

You may not park within 15 feet of a fire hydrant. Firefighters need clear, immediate access to the hydrant in an emergency.

Correct answer: Hold the wheel tightly, keep going straight, and slow down gradually

For a tire blowout, hold the steering wheel tightly and keep the vehicle going straight as you slow down gradually. Ease off the gas, brake lightly, and pull off the road in a safe place once slowed.

Correct answer: The driver on the right must yield to the driver on the left

When two drivers of large vehicles enter, exit, or drive in a roundabout at the same time, the driver on the right must yield the right-of-way to the driver on the left.

Correct answer: Overpasses, bridges and shaded areas

Overpasses, bridges, shaded areas and snow-packed portions of the road can be icy even when other pavement is clear, because they freeze first and thaw last.

Correct answer: 15 mph

Lane filtering allows a two-wheeled motorcycle to pass another vehicle in the same lane only when that vehicle and those in adjacent lanes are stopped, there is enough room, and the motorcycle travels no faster than 15 mph.

Correct answer: Laws and regulations that apply at a location; they are black or red on a white background

Regulatory signs tell you of laws and regulations that apply at a location. They are black or red on a white background, and failure to obey them is a traffic violation.

Correct answer: Affect the flow of traffic and create unpredictable, potentially unsafe situations

Driving much slower than the posted speed in normal conditions can affect the flow of traffic and create unpredictable, potentially unsafe situations.

Correct answer: An area slightly to the rear and side of your vehicle that you cannot see in your mirrors

A blind spot is an area you cannot see in your rearview or side mirrors, located slightly to the sides and rear of your vehicle. Look over your shoulder to check it before changing lanes.

Correct answer: Not a defense to a DUI or DWAI charge

The fact that marijuana or other drugs were used for medicinal purposes is not a defense for DUI or DWAI. If a drug impairs your driving, you can be convicted.

Correct answer: Either a 4-hour driver awareness program or a 30-hour driver education course

A minor 15½ to 16 must complete either a 4-hour driver awareness program or a 30-hour driver education course before the instruction permit.

Correct answer: A traffic signal, stop sign or railroad crossing

Parking is prohibited within 30 feet of a traffic signal, stop sign or railroad crossing, where a parked vehicle could block sightlines or the path of the control.

Correct answer: Keep your eyes on the road, shift to neutral, and pull off when safe

For a jammed gas pedal, keep your eyes on the road and quickly shift to neutral. Pull off the road when it is safe to do so, then turn off the engine.

Correct answer: All oncoming traffic, unless you have a green arrow or arrived first at a four-way stop

Before a left turn, look for and yield to pedestrians and smaller oncoming vehicles such as bicyclists and motorcyclists. You must yield to all oncoming traffic unless you have a green arrow or arrived first at a four-way stop.
