California CAR DMV Practice Test 21

If two vehicles arrive at the same time to an intersection that has stop signs on all corners, the vehicle to the right has the right-of-way.

"No zones" are areas around trucks or buses in which cars disappear into the larger vehicle's blind spots. "No zones" can also be defined as areas in which cars are so close to the larger vehicle that they restrict the truck or bus driver’s ability to stop and maneuver safely. A car being in a "No zone" greatly increases the potential for a crash.

When approaching a pedestrian who is using a white cane or guide dog while crossing the street, you must stop until the person is well away from your path of travel. Always yield the right-of-way to blind pedestrians.

To avoid being blinded when driving at night, do not look directly at the headlights of oncoming cars. Instead, look toward the right edge of the road until the oncoming driver has passed.

Within 100 feet of a railroad crossing where you cannot see 400 feet down the tracks in both directions, the speed limit is 15 mph. However, you may drive faster if the crossing is controlled by gates, a warning signal, or a flagger.

All temporary signs in work zones have an orange background with black letters or symbols. These signs are found on the right side of the road, or on both the left and right sides if the roadway is a divided highway.

Driving more slowly than other traffic can be dangerous. Drivers behind you may become impatient and will be tempted to take dangerous risks to pass you.

Motorcycles can be easily hidden in a vehicle’s blind spot or missed in a quick look due to their small size. Drivers of cars must always be alert and looking for motorcycles, mopeds, and scooters.

If you must stop on the shoulder of the interstate or highway, turn on your emergency flashers to warn other drivers and stay inside your vehicle, if you can. The extremely high speed of traffic makes standing or walking along an interstate highway very dangerous.

Warning signs are usually yellow with black markings. They alert you to conditions that are immediately ahead. This sign warns that you are leaving a separated one-way highway and will soon be driving on a two-way highway.

Freeway lanes that are ending will usually be marked by large broken lines painted on the pavement. If you are driving in a lane marked with these broken lines, be prepared to exit the freeway or for the lane to end.

Orange-colored signs indicate construction areas. Proceed with caution.

To prevent skidding on slippery surfaces, you should shift to a low gear before going down a steep hill. You should also follow farther behind the vehicle in front of you than you normally would. Quick stops should be avoided. Unless you have antilock brakes, pump the brakes to slow or stop.

Large trucks must often swing wide to complete a right turn. A truck making a right turn may initially appear to be turning left because of the need to swing wide. When behind a turning truck, you should pay attention to the truck's turn signal to be aware of which way the trucker actually intends to turn.

Unless otherwise posted, the speed limit in business and residential districts is 25 mph.

When a protected turn arrow changes from green to yellow, drivers must prepare to yield to oncoming traffic. A yellow arrow indicates that the protected left turn is ending.

When approaching a school bus that is picking up or dropping off passengers, you must come to a complete stop before reaching the bus, regardless of your direction of travel.

You should signal at least 100 feet before you turn, before every lane change, at least five seconds before you change lanes on a freeway, before pulling next to the curb or away from the curb, even when you do not see other vehicles around you, and when you are almost through the intersection if you plan to turn shortly after crossing the intersection. Remember to turn off your signal when you no longer need it.

You must have evidence of financial responsibility, such as proof of insurance, with you whenever you drive. You must always show proof of insurance and your license to an officer upon request after a traffic stop or collision.

Excessive speed is one of the most common contributing factors to vehicle crashes. Excessive speed does not save time and often leads to high-risk decision-making.

This is a low clearance warning sign. It indicates the distance from the road surface to the bottom of a bridge or overpass (in this case, 12 feet, 6 inches).

When you have a collision, report it to DMV within 10 days if anyone was injured (no matter how slightly) or killed. You or your representative must make this report whether or not you caused the collision, even if the collision occurred on private property.

A driver’s ability to safely operate a vehicle may be impaired at any BAC level, even a level lower than the legal limit. Any amount of alcohol can affect one’s judgment and physical coordination. Driving under the influence of even a small amount of alcohol can lead to criminal charges.

This sign indicates that a stop sign is ahead.

Warning signs are usually yellow with black markings. They alert you to conditions that are immediately ahead. This sign tells drivers to prepare to allow traffic to safely merge from the right.

You may encounter unexpected conditions in a construction zone. For the safety of yourself, other drivers, and construction workers, drive with extraordinary caution.

If you injure or kill an animal on the roadway, you should call CHP, the nearest humane society, or the police. You should not leave the animal to die or try to move the animal.

While waiting to turn left, keep your wheels pointed straight ahead until it is safe to start your turn. If a vehicle hits you from behind, this will prevent you from veering into oncoming traffic. When parked facing either uphill or downhill, turn the wheels so the vehicle will not roll into traffic if the brakes fail.

The posted maximum speed limit is the fastest legal speed you can travel on a road under ideal conditions. It is safest to drive at the same speed as surrounding traffic, up to the maximum speed limit. Maintaining a safe speed at all times is a responsibility shared by all motorists.

Regulatory signs inform drivers of specific laws that must be obeyed. Displayed laws may be about traffic direction, lane use, turning, speed, parking, or special situations. Regulatory signs are commonly white squares or rectangles with black, red, or green letters or symbols.
