The ability to drive safely is dependent on the driver being in good physical condition. Driving can be impaired by alcohol, legal and illegal drugs, and being drowsy.

Warning signs are used to warn drivers about upcoming hazardous conditions and are usually yellow with black markings. This sign tells drivers that they are approaching a school zone and that they should slow down and watch for children.

Passing on a two-lane, two-way road requires good judgment because you must use the lane belonging to oncoming traffic to complete your pass. Only pass if you may safely and legally do so.

Wet roads are always dangerous, but they are particularly dangerous at the start of a light rain. When it just begins to rain, the rain water mixes with oil and dirt that has not yet washed away from the surface of the road and creates a slippery film.

If you miss your exit, you should take the next exit. Do not stop or back up on the highway, swerve across multiple lanes to try to make the exit at the last second, or cross over the median to turn around. All of these maneuvers are illegal and extremely dangerous.

A regulatory sign displaying a red circle with a red slash through the middle indicates that a specific action is prohibited. Right turns are not permitted where this sign is posted.

If you arrive to an open intersection at the same time as a vehicle to your right, you should yield the right-of-way to that vehicle. You may then proceed when it is safe to do so.

Keeping a safe following distance will enable you to react to an upcoming problem without the need for a emergency stop, which could cause a driver behind you to crash into the back of your vehicle.

This advisory speed sign indicates the maximum safe speed for a highway exit (in this example, 30 mph).

If you are following another vehicle at a railroad crossing, check to make sure you have enough room to get all the way across before you drive onto the tracks. You should never try to pass another vehicle as you approach or cross a railroad crossing. Always check for trains before crossing any railroad tracks.

Construction and maintenance signs are orange-colored and are used to notify drivers of unusual or potentially dangerous conditions in or near work areas. This sign warns drivers that they are approaching a construction zone and that they should prepare to lower their speed and drive with extraordinary caution.

When turning, you should reduce to a speed that allows you to maintain control of your vehicle, stay in your lane, and react to unexpected situations.

When entering a roadway from a driveway or private road, you must yield the right-of-way to pedestrians and traffic on the roadway.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign alerts drivers to an upcoming intersection.

To complete a turn safely, you should activate your turn signal three to four seconds before your turn.

The amount of space you need to cross traffic depends on the road conditions, weather conditions, and oncoming traffic.

A triangular red and white yield sign means that you must decrease speed as you approach an intersection and yield the right-of-way to any vehicles or pedestrians in the intersection. You must be prepared to stop if conditions require it.

You should slow down at the first sign of rain, snow, or sleet, all of which can create slippery road conditions. When conditions on the road are less than ideal, safety may require that you drive more slowly than the posted speed limit.

Double solid yellow lines are used to mark roadways where passing is prohibited from both directions. You may cross these lines only to make a left turn into or from an alley, private road, or driveway.

Always be prepared to yield to any oncoming trains before crossing railroad tracks, particularly if there are no lights or gates controlling the crossing. Never start to cross the tracks until there is room for your entire vehicle on the other side of the tracks. Due to the risk of a vehicle stalling, it is not wise to shift gears when crossing railroad tracks.

If another vehicle is approaching you head-on in your lane, you should first honk your horn to attract attention. If the other driver does not move over, try to escape to the right. If you swerve left and the other driver corrects at the last instant, you will still crash. If a collision is unavoidable, brake firmly and steadily. Every mile per hour you slow down will reduce the impact.

Distractions cause drivers to react more slowly to traffic and hazards on the roadway. Distracted driving is never safe.

When intending to back up, always check behind your vehicle before getting in. Children and small objects are difficult to see from the driver’s seat. While backing, turn your head so you can see through the rear window. Do not depend only on your mirrors or sensors.

Drivers must always yield to pedestrians in the street, even if they are crossing against a red light or are otherwise being careless.

A speed limit is the maximum or minimum legal speed you can travel on a road under ideal conditions. You may drive more slowly than the posted speed, but it is illegal to drive any faster. You must drive more slowly where signs or signs indicate a school zone or work zone speed limit. If conditions such as road construction or bad weather make the posted speed unsafe, drive under the speed limit.
