This sign indicates that the road may be slippery when wet. Exercise caution when driving on a slippery road.

Low beam headlights should be used in fog, rain, and snow. The light from high beams will reflect back to the driver under these weather conditions, causing a glare that will make it difficult to see ahead.

You must stop at a railroad crossing if the gate is lowering. It is unsafe to do otherwise.

You must not pass a vehicle that is stopped at a crosswalk. There may be pedestrians crossing the street that you cannot see. Instead, stop, proceeding only after all pedestrians have crossed.

Yellow lines separate traffic moving in opposite directions. Dashed lines on the pavement indicate that passing is permitted when safe.

A flashing red light at an intersection means you must stop completely before proceeding. Treat a flashing red light the same as you would a stop sign.

The flashing overhead lights and stop arm on a school bus will be activated when the bus is stopped to load or unload students. If approaching a bus using these signals, you may not proceed until the red lights have stopped flashing and the stop arm has been retracted. Never pass a school bus that is dropping off or picking up students.

You should adjust your speed to travel smoothly with the other traffic on a roadway (provided that the other traffic is driving within the posted speed limits). Remember that vehicles moving in the same direction at the same speed cannot hit each other. Crashes involving multiple vehicles often happen when some vehicles are traveling at different speeds than others.

Yellow lines separate lanes of traffic moving in opposite directions. A broken yellow line next to your driving lane means that you may pass.

This sign warns of two-way traffic.

When it is difficult to see due to darkness or poor weather, increase your following distance. This will give you more time to react to hazards that you may not see in advance.

This sign informs drivers that they are leaving a divided roadway and approaching a two-way highway.

Downward-facing triangular signs mean drivers must yield. When approaching a yield sign, slow down to a speed that is reasonable for existing conditions and stop if necessary. If you must stop, do so at a marked stop line, if it exists.

When driving in fog, you should always use your low beam headlights. Using high beams will reduce visibility because the high beam lights will reflect back into your eyes.

Bicycles do not have turn signals so bicyclists use hand and arm signals to alert other drivers to their intentions. If a bicyclist puts their left arm straight out, they are signaling that they intend to turn left.

Your tires do not have as much traction on loose gravel and dirt roads as they do on concrete and asphalt roads. When driving on gravel or dirt, you must slow down. It will take you much longer to stop and it is much easier to skid when turning.

Yellow lines are used to separate traffic moving in opposite directions. Solid lines indicate that drivers are not permitted to pass.

When making any turn, turn from the lane closest to the direction you wish to travel into the first available legal lane. On a turn from a two-way to a one-way street, this means you should turn into the first lane.

This sign indicates that a divided highway begins ahead. Keep to the right of the median divider.

Watch for any pedestrian who may cross your path. If you see pedestrians near the road where you are driving, slow down and be prepared to stop, if necessary.

When following a motorcyclist, allow for at least a three- to four-second following distance. Motorcycles can stop quickly and following them too closely endangers your life and that of the motorcyclist. If the motorcyclist should fall, you need extra distance to avoid the rider. The chances of a fall are greatest on wet and icy roads, gravel roads, and metal surfaces such as bridges, gratings, and streetcar or railroad tracks.

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

To prevent yourself from becoming an aggressive driver, concentrate on driving and don't take the actions of other drivers personally. Be realistic about your travel time, drive within posted speed limits, and be forgiving of other drivers using the roadway.

Allow for extra space when driving behind a motorcycle. Motorcycles can stop more quickly than other vehicles can and you must have adequate room to stop if the motorcyclist brakes or falls off. Also, remember that motorcycles are difficult to see at night because they only have one tail light.

A triangular yellow sign with black lettering indicates a no passing zone. It will appear on the left side of a two-way, two-lane roadway at the beginning of an area where prohibitive pavement markings are also used.

Pedestrian crosswalks are often shown by white, solid lines to emphasize pedestrian crossing points. Crosswalks may have additional lines between the white, solid lines or in place of the parallel lines. However, crosswalks may also be unmarked.

School buses and tank trucks carrying hazardous materials must stop at all railroad crossings, regardless of the presence of a train. Be prepared to stop at all railroad tracks if following one of these vehicles.

Your safety and the safety of other drivers and pedestrians depends a lot on what you do before driving. Before moving your vehicle, you should adjust your seat, adjust your mirrors, fasten your safety belt, and secure items in and on your vehicle. Do not wait until your vehicle is moving to adjust your mirrors.

You should enter a freeway at or near the speed of traffic, unless the speed of traffic exceeds the legal speed limit.

Defensive driving is using safe driving strategies to prevent crashes. This means that you alter your driving to fit the weather conditions, the way you feel, and the actions of other drivers, bicyclists, and pedestrians.
