After coming to a full stop, vehicles should proceed through a four-way stop in the order in which they arrive to the intersection. If multiple vehicles arrive at the same time, the vehicle on the left must yield the right-of-way to the vehicle on the right.

While it can create special problems for large vehicles, strong wind can cause problems for all drivers. Wind can lower visibility by blowing dirt and dust into the roadway, but it can sometimes also physically move a vehicle.

If possible, try to only deal with one roadway hazard at a time. If you want to pass a pedestrian but an oncoming vehicle is approaching, slow down and let the vehicle pass. You may then pass the pedestrian if it is safe to do so.

Rumble strips create noise and vibrations to warn drowsy or inattentive drivers that they are straying off of the road or are approaching a stop sign or signal.

Warning signs are usually yellow with black markings. They alert you to conditions that are immediately ahead. These signs may be accompanied by speed advisory plaques that indicate the speed with which you should proceed.

If your vehicle leaves the roadway, hold the steering wheel firmly, release the gas pedal, and gently apply the brakes. Wait until your speed has reduced, check the traffic, and look for a place to safely return to the roadway by merging back into traffic. Overcompensating by jerking the wheel to return to the roadway can cause you to lose control of your vehicle or may cause your car to go into other lanes of traffic.

This sign indicates that you are approaching a railroad crossing. You must look, listen, slow down, and prepare to stop. Wait for any trains to pass before you proceed.

Use your low beams when driving in fog, snow, rain, or mist. Light from high beams will reflect off of precipitation, causing a glare and making it even more difficult to see. Some vehicles are equipped with fog lights that should be used in addition to low beam headlights.

Never pass within intersections or at other intersecting points, such as parking lot entrances and alleyways. Any time your view is blocked by a curve or a hill, you should stay in your lane and assume that there is an oncoming vehicle just out of sight. Wherever signs and/or pavement markings permit passing other vehicles, you will have to determine whether or not you have enough space to pass in a safe manner.

Regulatory signs provide notice to road users of traffic laws that must be obeyed. Where this sign is present, drivers must drive in the direction indicated by the arrow.

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.

Regulatory signs provide notice to road users of traffic laws that must be obeyed. This particular sign tells you the maximum speed limit for the stretch of highway where it is posted. You may drive more slowly than the posted speed limit, based on road conditions, but it is illegal to drive any faster than the posted speed limit.

Slow-moving vehicles, such as farm tractors, road maintenance vehicles, and animal-drawn carts, display an orange and red triangle on the back.

To avoid the need for last-minute braking or turning, consistently watch the road far ahead of your vehicle. By looking ahead and being ready to stop or change lanes if needed, you can drive more safely, save fuel, and help keep traffic moving at a steady pace.

If you come across a "No passing zone" sign, it is not legal to pass in the indicated area. You are likely driving in an area with restricted visibility where it would be unsafe to pass another vehicle.

Any amount of alcohol acts as a depressant, slowing the function of the nervous system. It will reduce a person's alertness and ability to concentrate, increase their reaction time, and drastically reduce their coordination.

Motorcyclists have the right to use a complete traffic lane, but two motorcyclists may share a lane if they choose to do so. Do not pass a motorcycle within the same lane.

It can be hard to judge the speed of oncoming vehicles. They do not always seem to be coming as fast as they really are. Always be sure you can safely change lanes when passing on a two-lane street. If you are not sure of an oncoming vehicle's speed, wait to pass until the oncoming vehicle has passed and you are sure there is enough space for you to change lanes safely.

Alcohol is a depressant that dulls your judgment and makes your reflexes unreliable.

Warning signs provide notice to road users of a situation that might not be readily apparent and are usually yellow with black markings. This sign warns drivers of an upcoming intersection so they may prepare for potential traffic or prepare to turn.

Blood alcohol concentration (BAC) is a measurement of the percentage of alcohol in the blood. The higher the BAC number, the more impaired a person is.

Warning signs provide notice to road users of a situation that might not be readily apparent and are usually yellow with black markings. This sign warns drivers of an upcoming steep hill. Drivers should adjust their speed accordingly to avoid collisions and brake damage.

Legal medications, both prescription and over-the-counter, can impair your ability to drive. They can be particularly dangerous when used in combination with alcohol.

Warning signs are usually yellow with black markings. This sign warns the driver that there is an upcoming winding road. Speed should be adjusted appropriately.

You should always signal when turning, changing lanes, slowing down, or stopping so that other drivers, motorcyclists, bicyclists, and pedestrians will know your intentions.
