A reflective orange triangle on the rear of a vehicle means the vehicle often moves at speeds of 25 mph or slower. You may see this decal on construction equipment, farm vehicles, and horse-drawn wagons or carriages.

Warning signs are normally diamond-shaped and yellow, although orange warning signs are used in work areas. Such signs warn that you are approaching a hazardous location or an area where special rules apply.

These signs indicate that the road curves to the right ahead and that drivers should slow down to the safe speed indicated (in this case, 35 mph).

This sign prohibits U-turns. Do not make a U-turn where this sign is posted.

This sign means that a traffic signal is ahead. You should slow down and be prepared to stop.

This signs indicate that U-turns are prohibited in the location where it is posted.

This sign warns of an upcoming winding road with three or more curves.

This sign warns that a road has one-way traffic and you must not enter from your current direction.

The faster you drive on a wet roadway, the less effective your tires will be at wiping the water from the road. If your speed becomes excessive enough, your tires will lose their grip on the road entirely and you will begin to hydroplane (that is, to slide down the road on a film of water).

Arrows may be used to indicate which lanes should be used for specific purposes, such as driving straight or making a turn.

When you see any signs indicating a nearby railroad crossing, you should slow down, look for a train, and be ready to stop. If the red warning lights are flashing or the gate is down, you must stop 15 to 50 feet before the railroad tracks. Do not try to go around the gate.

Lap belts should fit snugly across your hip bones and the lower part of your abdomen. Shoulder belts should sit comfortably so that you can insert your fist between the belt and your chest.

In cold or wet weather, you should take special care on sections of road that are shaded by trees or buildings. These areas freeze more quickly than the rest of the road and are the last parts of the road to dry.

To check your blind spot before changing lanes, you should look over your shoulder in the direction that you plan to move.

The most important thing to remember about driving in curves is that your vehicle’s inertia may make it difficult to turn. To maintain control, it is essential that you slow down before entering the curve.

A green arrow displayed on a traffic signal tells drivers that they may turn in the direction of the arrow. You must be in the proper lane for such a turn. Yield the right-of-way to vehicles and pedestrians already in the intersection.

Driving more slowly than the flow of traffic can be hazardous. If you are on a two-lane, two-way road and driving so slowly that traffic is backing up behind you, you are required to pull off the road and let the other vehicles pass. Only drive significantly under the speed limit when conditions require it.

To prevent drowsiness on long trips, you should schedule regular stops. Give yourself time to rest and stretch, even if you are not feeling tired.

When stopped at an intersection, you should first look to your left, as vehicles coming from the left are closer to you than vehicles coming from the right. Look to your right, then look to your left again, in case there are any vehicles coming from that direction that you did not see at first glance.

This sign is used with a traffic signal to tell drivers that left-turning traffic does not have the right-of-way and must instead wait for oncoming traffic to clear.

The faster you drive, the smaller your field of vision becomes. As your speed increases and your field of vision decreases, you must be extra alert to potential hazards.

The combination of alcohol and drugs, in some cases, can increase the effects of both the drugs and alcohol. It can be unsafe to drive after consuming either alcohol or drugs and is even more dangerous after combining them.

Pavement can become very slippery within the first 10 to 15 minutes of a rainstorm because the rain causes oil in the asphalt to rise to the surface of the road. This problem becomes even worse in hot weather. The heat combined with the water causes more oil to rise to the road surface.

This sign warns that deer cross the roadway in the area. You should slow down, be alert, and be ready to stop.

Special child seats are available for children who are too small to wear regular safety belts. No person is strong enough to safely hold onto a child of any size during an accident or sudden stop. Never allow a child to ride in a vehicle unless they are properly fastened into a seat.
