DMV Written Test Prep Practice Test

Explanation: You must always yield the right-of-way to pedestrians in crosswalks, regardless of whether it's marked or unmarked, and when they are crossing with a 'Walk' signal. Pedestrians always have the right-of-way when they are legally in a crosswalk or intersection.

Explanation: A yield sign means you must slow down and be prepared to stop if necessary to allow other traffic or pedestrians to proceed. You only proceed when it is safe to do so without interfering with other traffic. Unlike a stop sign, a complete stop is not always required if the way is clear.

Explanation: If you miss your exit on a freeway, you should continue to the next exit. It is extremely dangerous and illegal to stop, back up, or try to cross multiple lanes to get back to a missed exit. Plan your route carefully and proceed to the next safe exit.

Explanation: A broken white line on the road indicates that you may change lanes if it is safe to do so. It separates lanes of traffic moving in the same direction. A solid white line means lane changes are discouraged or prohibited, and yellow lines separate traffic moving in opposite directions.

Explanation: The proper hand signal for a left turn is to extend your left arm straight out horizontally. For a right turn, the left arm is extended upward. For slowing down or stopping, the left arm is extended downward. Hand signals are used when turn signals are not working or to reinforce intentions.

Explanation: Under ideal driving conditions, the minimum safe following distance is typically considered to be a '3-second rule' for passenger vehicles. This allows enough time to react and stop if the vehicle ahead suddenly brakes. The '2-second rule' is often taught as a minimum, but 3 seconds provides a safer buffer.

Explanation: When parallel parking, your vehicle should generally be parked within 12 inches of the curb. This ensures that your vehicle is not obstructing traffic and is legally parked. Parking too far from the curb can be a safety hazard and may result in a citation.

Explanation: The 'two-second rule' is a simple way to estimate a safe following distance between your vehicle and the vehicle in front of you. You should allow at least two seconds of travel time between your car and the car ahead. In adverse conditions (rain, snow, heavy traffic), this distance should be increased to three or more seconds.

Explanation: When parking uphill with a curb, you should turn your front wheels away from the curb. This way, if your brakes fail, the vehicle will roll back into the curb and stop, preventing it from rolling into traffic. When parking downhill with a curb, turn your wheels towards the curb.

Explanation: If you are involved in an accident, the immediate priorities are to stop safely, render aid if needed, and exchange information with the other parties involved. Leaving the scene of an accident is illegal. Calling your insurance company is important but comes after ensuring safety and exchanging information.

Explanation: On multi-lane highways, the left-most lane is generally designated for passing slower vehicles. Drivers should move to the right lanes when not passing to allow faster traffic to flow. It is not primarily for slower traffic or continuous driving.

Explanation: If your brakes fail, the first thing you should do is pump the brake pedal hard and fast. This might build up enough pressure to get them working again. If that doesn't work, shift to a lower gear to use engine braking, and then use the emergency/parking brake carefully.

Explanation: If your vehicle starts to hydroplane, you should ease your foot off the gas pedal, keep the steering wheel straight, and avoid braking suddenly. Allow the vehicle to slow down naturally until your tires regain traction. Sudden braking or steering can cause you to lose control.

Explanation: Regulatory signs inform drivers of traffic laws and regulations that must be obeyed. Examples include 'Stop,' 'Yield,' 'One Way,' 'Speed Limit,' and 'No Parking' signs. Warning signs alert to hazards, guide signs provide directions, and informational signs offer general information.

Explanation: The primary purpose of seat belts is to keep you safely secured in your seat, preventing you from being thrown forward or ejected from the vehicle during a sudden stop, collision, or rollover. They significantly reduce the risk of serious injury or death.

Explanation: A yellow diamond-shaped sign with a black arrow curving to the right indicates a curve to the right ahead. These signs are warning signs, alerting drivers to potential hazards or changes in road conditions. It is not indicating a right turn only lane, a sharp turn, or a detour.

Explanation: When preparing for a right turn, you should get as close as possible to the right curb or edge of the road. This positions your vehicle correctly for the turn, prevents other vehicles from trying to pass on your right, and helps ensure a smooth and safe maneuver. Signaling at least 100 feet before the turn is also crucial.

Explanation: A flashing red traffic light means the same as a stop sign. You must come to a complete stop before the intersection, and then proceed only when it is safe to do so. It does not mean to slow down or yield, but to stop completely.

Explanation: When an emergency vehicle with flashing lights and sirens approaches, you must safely move to the right edge of the road and stop. Remain stopped until the emergency vehicle has passed. Do not stop in the middle of an intersection or block their path.

Explanation: When driving in fog, you should use your low-beam headlights. High beams will reflect off the fog and worsen visibility, making it harder to see. Fog lights, if available, can also be used, but low beams are essential for improving visibility without causing glare.

Explanation: Passing on the right is generally allowed only when the vehicle ahead is making a left turn, or on a roadway with unobstructed pavement of sufficient width for two or more lines of vehicles moving in the same direction. It is not permitted on shoulders or when the vehicle ahead is turning right. This rule ensures safety and prevents unexpected maneuvers.

Explanation: A pedestrian carrying a white cane, or a white cane tipped with red, indicates that the person is blind or visually impaired. Drivers must always yield the right-of-way to these pedestrians and exercise extreme caution to ensure their safety.

Explanation: White rectangular signs with black lettering are typically regulatory signs. They convey traffic laws and regulations that drivers must obey, such as speed limits, 'No Parking,' 'One Way,' or 'Do Not Pass' instructions. Yellow signs are for warnings, green for guidance, and blue for motorist services.

Explanation: A green arrow displayed with a red traffic light means that you may proceed carefully in the direction of the arrow, even if the main light is red. You must yield to any vehicles or pedestrians in the intersection. It does not mean to stop or wait for a full green light.

Explanation: You are required to use your turn signals whenever you are changing lanes, turning, or merging into traffic. This communicates your intentions to other drivers and helps prevent accidents. Signaling is not optional based on traffic volume.

Explanation: To avoid blinding oncoming drivers, you should dim your high-beam headlights when an oncoming vehicle is within 500 feet (approximately one-tenth of a mile). You should also dim them when following another vehicle within 200-300 feet.

Explanation: In all U.S. states, the legal blood alcohol concentration (BAC) limit for drivers 21 years of age and older is 0.08%. Driving with a BAC at or above this limit is considered illegal and can result in severe penalties. For drivers under 21, the limit is typically much lower, often zero tolerance.

Explanation: When a school bus has its red lights flashing, it indicates that children are getting on or off the bus. You must stop your vehicle before reaching the bus, regardless of your direction of travel, unless you are on a divided highway with a physical barrier between you and the bus. You must remain stopped until the lights stop flashing and the bus begins to move.

Explanation: A 'Do Not Enter' sign indicates that you are not allowed to enter a road or ramp. This is typically used to prevent wrong-way driving on one-way streets or freeway ramps. Disregarding this sign can lead to head-on collisions and severe accidents.

Explanation: A solid yellow line on your side of the center line indicates a no-passing zone for traffic traveling in your direction. You are not permitted to cross it to pass another vehicle. A broken yellow line allows passing if safe, and a solid white line indicates lane boundaries or shoulder.
