You should turn your head to check your blind spots before every lane change.

Good drivers try to see 10 to 15 seconds ahead on the roadway. By looking ahead, you may avoid unnecessary last-minute moves, such as sudden stops or quick lane changes.

If you come to a roadway that is flooded, turn around and find another way to go. Do not attempt to drive through the water. It is impossible to determine the depth or current and your vehicle could become submerged or swept away.

Be prepared to reduce your speed and use caution when directed to do so by a sign, crossing guard, or law enforcement officer. Always drive with extra caution in a school zone.

If you must drive in foggy conditions, you should use your low beam headlights, as well as your fog lights, if your vehicle has them. High beams direct their light upwards, where it can bounce off the fog and into your eyes, reducing visibility even more.

This sign indicates that a steep downhill grade is ahead.

This sign warns that there is a steep hill ahead.

Warning signs are used to warn drivers about upcoming hazardous conditions and are usually yellow with black markings. This sign warns drivers that an upcoming bridge may be too narrow to meet or pass a truck and that they should be careful.

If your vehicle breaks down on the highway, you should signal before carefully exiting the roadway and turning on your hazard flashers. Get as far off the road as possible and park in a location where other drivers can easily see you. Lift your hood to let other drivers know your vehicle is disabled.

A steady yellow light on a traffic signal indicates that a steady red light will soon appear.

Many over-the-counter medications can affect your ability to drive safely. If you take medication, even a remedy for colds or allergies that is not prescribed, check the label for warnings about its effects. If you are unsure, ask your doctor or pharmacist about driving while on the medication.

Regulatory signs are white, rectangular signs with black markings. Drivers must obey the instructions posted on all regulatory signs. Where this sign is posted, it is prohibited for drivers to pass one another.

You may not pass another vehicle on a hill or in a curve because you cannot see oncoming traffic and may cause a collision. Never pass another vehicle by driving onto the shoulder of a highway. Passing another vehicle by driving over a solid yellow line is prohibited.

This sign indicates that the shoulder is lower than the road in the area ahead. If you drift off of the roadway and one wheel drops onto a low shoulder, do not slam on the brakes or steer sharply to try to get back onto the roadway. This could easily cause you to lose control of your vehicle.

You should slow down as you enter a curve and increase your speed gradually as you exit. Increasing your speed as you enter a curve will make it more difficult to control your vehicle.

This sign indicates that you must keep to the right of the upcoming divider.

Curve and turn warning signs often have attached advisory speed signs that show a recommended driving speed for drivers in the curves and turns. Although a driver may feel comfortable driving at a higher speed in fair weather, they should never do so under rainy, snowy, or icy conditions.

Warning signs are used to warn drivers about upcoming hazardous conditions and are usually yellow with black markings. This sign warns drivers that the road ahead curves to the right and then to the left.

When driving on a two-lane roadway or undivided highway, you must yield to an emergency vehicle using its lights and/or siren, regardless of the direction from which it is approaching. Immediately drive as near as possible to the right side of the road and stop, taking care not to stop within an intersection.

Many crashes are caused by drivers who are driving too fast for conditions. Always drive within the legal speed limits and decrease your speed any time conditions are less than perfect.

Double solid lines indicate that you may not pass or change lanes. You cannot cross the lines unless it is to turn left to enter or exit a highway, to turn into or from a driveway, or to make a U-turn (where permitted).

This triangular sign is a "Yield" sign. When you see this sign, you must slow down to check for traffic and yield the right-of-way to pedestrians and approaching cross traffic. Stop only if it is necessary to do so.

If you miss your turn or exit, do not back up, but go on to the next turn or exit where you can safely turn around. It is illegal to back up on a shoulder or a freeway.

Highway markings provide information for drivers. Markings help drivers correctly position their vehicles on roadways, inform drivers of safe passing zones, and warn drivers about upcoming conditions.

In certain cases, the DMV can suspend your license if you are convicted of driving at speeds higher than 75 mph. Passing a stopped school bus, driving without a license, or failing to yield the right-of-way will incur points, which can lead to suspension of your license if enough total points are incurred.

When other drivers are behaving angrily, you should take action to physically and mentally distance yourself from the situation. Avoid making eye contact with them, or making body movements or gestures that could provoke them. Slow down, move over, or do whatever you safely can to put yourself out of danger.

Distracted driving is extremely risky behavior that puts not only you and your passengers in danger, but also endangers pedestrians, bicyclists, and other motorists sharing the road. Focused attention on driving helps to prevent crashes.

This sign indicates that the road ahead curves to the right and then to the left. You should slow down to be able to negotiate these curves safely.

If you approach an emergency vehicle, tow truck, or roadside assistance vehicle that is stopped with its lights flashing, you must change lanes to allow the vehicle extra space. If there is only one lane moving in your direction, or if changing lanes would be unsafe, you must slow down to a speed below the posted speed limit and give the stationary vehicle as much room as possible. Always slow down and be prepared to stop when you approach an emergency scene.

Regulation signs regulate traffic speed and movement, displaying rules which drivers must obey. This regulation sign means that right turns are prohibited.

When using a freeway exit ramp, do not slow down until you move onto the exit ramp.

In snowy weather, keep your windshield and mirrors clear. Increase your following distance when driving in wet and cold weather because a slippery road surface will increase the distance needed for your vehicle to stop.

To prevent hydroplaning, you should ensure that the tires on your vehicle have good tread depth and are inflated to the proper pressure. Reduce the speed of your vehicle when driving in the rain. Hydroplaning occurs most frequently at higher speeds.

Regulation signs regulate traffic speed and movement, displaying rules which drivers must obey. This regulation sign indicates that drivers turning left at a green light must yield to oncoming traffic and may complete the turn when it is safe to do so.

This sign indicates that there is a flagger ahead controlling traffic in a construction area.

Adjust the inside mirror so you can see the entire rear window from the driver's seat. You should have to move only your eyes, not your head, when using this mirror.

You should not use cruise control on snow, in rain, in fog, or under similar hazardous conditions. Winter is the most difficult driving season and requires extra caution from drivers. It is important to consistently check your antifreeze and windshield washer fluid levels. Using snow tires can increase a vehicle's traction on the surface of slippery roads.
