Topic overview

Interstates are built for steady, high-speed travel: access is limited to interchanges, and there are no stop signs, railroad crossings, or traffic lights to interrupt the flow. This section is about driving these roads with confidence — entering smoothly, keeping a safe following distance, and leaving at the right exit. A little planning before you start goes a long way.

Merging is where many drivers get nervous. Use the acceleration lane to build up to the speed of traffic, signal your intent, and remember that you must yield to cars already on the interstate. Never drive to the end of the on-ramp and stop — you'll have no room to reach highway speed and risk being rear-ended. Once you're on, keep to the middle of your lane, stay out of blind spots, and leave the far-left lane for faster or passing traffic.

Long-distance driving brings its own challenges. Fatigue and the steady hum of the road can lead to "interstate hypnosis," so keep your eyes moving, take a break every couple of hours, and stop if you feel drowsy. Know how to leave safely — plan your exit early and slow down only in the deceleration lane, never on the through lanes. And if you ever break down, this section covers Tennessee's Move Over Law and what to do when a vehicle is stopped on the shoulder.

How far behind should I follow on the interstate?

Stay at least two seconds behind the vehicle ahead, and increase that to a minimum of four seconds in bad weather, at night, or on high-speed rural stretches. It also helps to scan 15 to 20 seconds ahead so you spot cars braking, entering, or exiting in time.

What do I do if I miss my exit?

Simply continue to the next exit. It is illegal to back up, make a U-turn, or cross the median on an interstate, so never try to reach a missed exit. Exit signs are usually posted at least a mile ahead, which gives you time to move into the right lane early.

Who is allowed to use the HOV lane during peak hours?

During peak commuting hours, the HOV lane is reserved for vehicles carrying two or more people, buses with two or more occupants, motorcycles, and emergency vehicles. A baby in a car seat counts as a passenger. Driving alone in the HOV lane during those hours — even just to pass — can bring a fine.

- Drivers must obtain a special permit to enter the interstate
- Only commercial vehicles are allowed to use it
- Traffic must stop at frequent intersections along the way
Explanation: Limited or controlled access means drivers can only enter or leave the roadway at entrances and exits called interchanges, without ever crossing the path of other traffic.

What major type of collision have interstates and divided highways largely removed?
- Head-on collisions — Correct answer
- Parking lot fender-benders
- Collisions at railroad crossings
- Collisions with pedestrians at crosswalks
