Only use your horn when it is necessary to avoid collisions. Do not use your horn if a driver or bicyclist is moving slowly and you want him or her to drive faster or get out of your way.

Abuse of a disabled placard or plate is a misdemeanor. Placard abuse can result in the loss of special parking privileges, a fine of up to $1,000, and up to six months of jail time.

All roads are slippery and dangerous when wet. This sign warns of conditions that can cause a driver to lose control of a car. A driver should slow down when coming upon wet pavement because it takes longer to stop.

Driving at night is more hazardous than daytime driving because the lowered visibility makes it difficult to judge speed, distances, and other potential hazards. Increase your following distance to help prevent a potential collision if the vehicle in front of you should stop abruptly. Use your headlights when driving at night, following the rules for proper usage of high beams and low beams.

Turn on your headlights when it is cloudy, raining, snowing, or foggy. If weather conditions require you to use your windshield wipers, you are required to turn on your low beam headlights.

Treat a flashing red light the same as a stop sign. Come to a complete stop at the stop line or, if there is no stop line, prior to the crosswalk and before entering the intersection. Yield to all other traffic and pedestrians.

If you can see a collision ahead, warn the drivers behind you by turning on your emergency flashers or by tapping your brake pedal quickly three or four times.

When driving, watch for warning signs of fatigue. You are too tired to drive safely if you are struggling to keep your eyes open, drifting from your lane, or turning up the radio and rolling down your windows to keep yourself awake. If you notice these signs, it is a good idea to find a safe place to park so you can refresh yourself with a short nap.

You may turn left onto a one-way street that moves to the left if there is no sign prohibiting the turn. You may not turn left onto a one-way street where traffic moves to the right.

Do not go around or under any lowered gate at a railroad crossing. Once the gate is raised, do not proceed across the tracks until you can see clearly in both directions and are sure there are no trains coming.

You must never turn around while on or near any curve or hill. You may not be able to see oncoming traffic or pedestrians and may cause a collision.

Diamond-shaped signs are used to warn drivers of special conditions or hazards ahead. They are typically yellow or orange in color.

If there are oncoming vehicles to your left and a row of parked vehicles to your right, the best thing to do is to split the difference. Steer a middle course between the oncoming cars and the parked cars.

You must approach all railroad crossings with extreme caution and cross only when you know that no train is coming from either direction. Be aware of vehicles that must stop at all railroad crossings, such as school buses and trucks carrying hazardous materials.

Alcohol, in any concentration, is a depressant. It slows all nerve impulses and bodily functions, resulting in a lessening of inhibitions and negatively affecting a consumer's ability to concentrate and stay alert.

Any time you come to a place where people may cross or enter your path, or where one line of traffic meets another, you should look to the left and right sides of your vehicle to make sure no one is coming.

If your vehicle has a two-part seat belt system, be sure to wear both the lap belt and the shoulder belt. Wearing either part alone greatly reduces your protection. If you have an automatic shoulder belt, be sure to buckle your lap belt as well.

Yellow signs with black markings are used to warn drivers about upcoming hazards or special conditions. Round signs are used only to warn about upcoming railroad crossings.

A broken yellow line in the center of the road indicates that traffic next to the broken yellow line may pass, if it is safe to do so.

You must yield to pedestrians at all times. If the pedestrians are jaywalking or crossing the street where they should not be, you must still stop for them.

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.

If you need to stop after crossing railroad tracks, wait until you can completely cross the tracks before proceeding. Make sure your vehicle clears the tracks before you stop.

You are driving defensively when you are looking down the road for potential hazards. Constantly staring at the road directly in front of your vehicle is dangerous. As you scan ahead, be alert to vehicles around you.

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.

When you are making a right turn, you must enter the bicycle lane no more than 200 feet before the corner or driveway entrance. Do not drive in the bicycle lane at any other time

A diamond-shaped sign on a truck means that the load on the truck is potentially dangerous (containing gas, explosives, etc.). Vehicles displaying these signs are required to stop before crossing railroad tracks.

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.

If you are in an intersection when you see an emergency vehicle approaching while using its flashing lights and/or siren, continue through the intersection and then drive to the right and stop. You must yield the right-of-way to any police vehicle, fire engine, ambulance, or other emergency vehicle using a siren or flashing lights.

When a vehicle makes a turn, the rear wheels follow a shorter path than the front wheels. The longer the vehicle, the bigger the difference between the paths of the front and rear wheels. Therefore, long trucks often have to swing wide to complete a right turn.

You need a longer distance to stop your vehicle on a slippery road than you do on a dry road. Maintain an increased following distance when driving on slippery roads.

This sign marks a one-way road, entrance, or exit. If you are facing this sign, traffic is coming toward you. Turn around if you are driving toward this sign.

Your emotions affect your ability to drive safely. If you are overly angry, excited, afraid, worried, or depressed, you should give yourself time to calm down before operating a vehicle. You need to be able to mentally focus on driving without thinking about the things that made you upset.

It is not always easy to maintain a safe distance behind your vehicle. However, you can help keep the driver behind you a safe distance away from your vehicle by maintaining a steady speed and signaling turns, lane changes, and deceleration in advance.

Any person, while operating a motor vehicle, who willfully flees or attempts to evade a peace officer performing his or her duties is guilty of a misdemeanor punishable by imprisonment in a county jail for not more than one year.

An animal must not be transported in the back of a pickup or other truck unless the animal is properly secured to prevent it from falling, jumping, or being thrown from the vehicle.

Keeping space around your vehicle is important to ensure that you have time to safely react if another driver makes a mistake. For example, extra space around your vehicle may give you time to brake or maneuver out of the way of a vehicle veering into your lane.
