Unless otherwise posted, the speed limit on primary and secondary state and federal highways in Tennessee is 55 miles per hour.

Where there are both solid and dashed yellow lines between lanes of traffic, only traffic directly next to the dashed line may cross the centerline to pass. Drivers next to the solid line may not pass.

Before changing lanes, check for drivers trying to pass you who may be trying to enter the same lane as you. Look over your shoulder to check your blind spot. You should never attempt to pass or otherwise change lanes in an intersection.

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.

It is illegal to cross the centerline to pass when driving on hills, in curves, and in other locations where you cannot see ahead far enough to pass safely. You may not pass at street crossings, at railroad crossings, where signs indicate no passing zones, or where a solid yellow line is next to your lane. You may not pass when the vehicle in front of you has stopped for a pedestrian or when driving in work zones where passing would be hazardous.

All temporary signs in work zones have an orange background with black letters or symbols. These signs are found on the right side of the road, or on both the left and right sides if the roadway is a divided highway.

Diamond-shaped signs are used to warn drivers of special conditions or hazards ahead. They are typically yellow or orange in color.

Alcohol takes effect quickly and is slow to leave your system. Cold showers, black coffee, and exercise will do nothing to reduce a person's blood alcohol content (BAC). The only way to lower your BAC is to wait.

Never attempt to drive on a flooded road. Even if the water looks shallow, it may hide many kinds of hazards. If you encounter a flooded area, turn around and seek another route to your destination.

If you become tired while driving, it is best to stop to rest or change drivers. Being tired dulls your mind and slows down your reactions, making driving hazardous.

All roads are slippery and dangerous when wet. This sign warns of conditions that can cause a driver to lose control of a car. A driver should slow down when coming upon wet pavement because it takes longer to stop.

Driving at night is more hazardous than daytime driving because the lowered visibility makes it difficult to judge speed, distances, and other potential hazards. Increase your following distance to help prevent a potential collision if the vehicle in front of you should stop abruptly. Use your headlights when driving at night, following the rules for proper usage of high beams and low beams.

When entering the interstate on a short entrance ramp where there is no acceleration lane, speed up only after you have identified a gap in traffic. In general, you should be stopped while waiting for a gap to appear.

When encountering a flashing yellow light at an intersection, you should slow down and proceed with caution. You do not need to come to a complete stop when approaching a flashing yellow light.

This sign warns of two-way traffic.

A truck's blind spots are much larger than a smaller car’s blind spots. The driver cannot see your car behind their vehicle and you can't see what’s happening in traffic ahead if you're driving too closely behind the truck. Whether you are driving behind or to the side of the truck, if you can’t see the driver’s face in their side view mirror, then they can’t see you.

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.

Drivers should check their rearview mirrors often to stay aware of the position of traffic behind them.

Every time you want to change lanes or otherwise move your vehicle to the right or left, signal to alert other drivers to your intentions. Always check your mirrors and turn your head to check your blind spot before attempting any lateral move.

Driving defensively means anticipating potential errors made by others and preparing to compensate for their mistakes.

When driving during unfavorable weather conditions, avoid slamming on the brakes and making sharp, quick turns. These behaviors will make controlling your vehicle in inclement weather even more difficult.

Children are often the least predictable pedestrians and the most difficult pedestrians to see. Take extra care to look out for children, especially near schools, bus stops, playgrounds, parks, and ice cream trucks. Be aware of children riding bikes on the sidewalk, as they may come onto the road unexpectedly.

You must stop at a railroad crossing when directed to do so by a flagger, stop sign, or warning signal. Use caution when driving near railroad tracks.

If you are being followed too closely by another driver, merge into a different lane. If there is no lane available for merging, wait until the road ahead is clear and slowly reduce your speed. This will encourage the tailgater to drive around you.

Excessive speed is one of the most common contributing factors to vehicle crashes. Excessive speed does not save time and often leads to high-risk decision-making.

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