An arrow painted on the pavement within a traffic lane indicates that drivers in the lane must make the movement indicated by the arrow. Drivers should follow directions given by any traffic signs or signals before proceeding in the direction indicated by the arrow.

Locations where it is unlawful and unsafe to pass another vehicle include hills, curves, intersections, and railroad crossings.

Wearing your seat belt is the single most effective thing you can do to reduce your risk of death or injury while driving.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign warns drivers that they are approaching a T intersection and should prepare to turn either right or left.

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.

To ensure that you will have time to react to hazards on the roadway, it is best to keep a cushion of space on all sides of your vehicle. Do not crowd vehicles to your left and right sides.

This sign indicates that the road that you are on intersects with a divided highway. A divided highway is two one-way roadways separated by a median or guide rail.

Yield the right-of-way to any approaching emergency vehicle that is using its flashing lights or siren, regardless of its direction of travel. You must immediately drive to the right side of the road and stop until the emergency vehicle has passed. If you are within an intersection, pass through the intersection before coming to a stop on the right side of the road.

You must yield to any transit vehicle that is signaling to pull back onto the main roadway after it has stopped to load or unload passengers. Change lanes, slow down, or stop to allow the bus safe re-entry into traffic.

Crosswalk lines show pedestrians where to safely cross a road or street. Crosswalks may be marked by horizontal lines, vertical lines, or a combination of the two. You must always stop for pedestrians who are in a crosswalk.

Double solid yellow lines in the center of the road mean that passing is not allowed from either direction. You may not cross the lines unless you are making a left turn or passing pedestrians, bicyclists, and riders of scooters or skateboards when the opposite lane is clear and you can pass safely.

Colorado drivers are required to have license plates attached to both the front and rear of the vehicle. Any motor vehicle owned by a Colorado resident cannot be parked or driven on a public street or highway unless it is properly registered and displays license plates.

Highway work zones are established according to the type of work underway along the roadway. Signs in work areas are typically diamond-shaped, orange, have black letters or symbols, and serve as a warning that people are working on or near the highway.

Any defect that may affect the safe operation of a vehicle should be corrected as soon as possible. Defects should be corrected before the vehicle is driven.

A flashing red traffic light has the same meaning as a stop sign. You must stop, yield the right-of-way, and go once it is safe.

When the driver behind you wants to pass, you should slow down so that there is enough room in front of your vehicle for the other driver to complete their pass. This will allow them to complete the passing maneuver in less time and more easily.

Always slow down before reaching a curve and accelerate only after passing the middle of the curve. If you drive too fast, the tires will not be able to grip the road and your vehicle will skid.

You must always signal before turning or changing lanes. You should keep your wheels straight while waiting to make a left turn. If another vehicle hits you from behind, this ensures that you will not be pushed into oncoming traffic.

You must stop at a railroad crossing when directed to do so by a flagger or stop sign. Stop when flashing red signals and gates are present and operating.

When driving to an unfamiliar area, plan your trip in advance. Don’t start with only a hazy idea of where you are going. If your destination is in an unfamiliar area, check the location on a map before you start to drive.

Your turn signals should always be used when you make any movement to the left or right. You should use your signal when pulling into traffic from a curbside parking space, moving into a new lane, or passing another vehicle.

Upon striking an unattended vehicle, stop and try to locate the owner. If you cannot find the owner, leave a written notice containing your name, your address, and the circumstances of the accident.

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).

Reducing your speed should be your first response to decreased visibility and dangerous road conditions.

Some highways reserve the left lane for vehicles with two or more occupants. These High Occupancy Vehicle (HOV) lanes are indicated by signs and diamond pavement symbols and are separated by a striped buffer zone.
