Passing and meeting large vehicles — Tennessee Permit Test
Passing and meeting large vehicles on the Tennessee permit test — 4 rules, each with the reason behind it and a question on it while it is fresh.
The rules
If a truck or bus driver blinks the headlights after you pass, it is a signal that you are clear to pull back in front.
The truck driver can see the gap better than you can. The flash tells you there is room, but still check for its front in your mirror.
If the truck or bus driver blink their vehicle headlights after you pass, it’s a signal that you are cleared to pull back in front of their vehicle.
When you meet a truck or bus coming the other way, keep as far right as possible to avoid being sideswiped and to reduce wind turbulence.
The rush of air between two passing vehicles can shove your car sideways. Extra room keeps a small wobble from becoming a crash.
When you meet a truck/bus coming from the opposite direction, keep as far as possible to the right of the road to avoid being sideswiped and to reduce wind turbulence between vehicles.
The wind turbulence between a car and a passing truck pushes the vehicles apart; it does not suck them together.
Expecting a pull toward the truck, a driver may steer into it. The real push is away, so hold the wheel steady.
The turbulence PUSHES vehicles APART. It does NOT suck them together.
When a truck is passing you, help the driver by keeping to the far side of your lane and slowing slightly; never speed up as a truck or bus passes.
Speeding up traps a truck in the passing lane, sometimes facing oncoming traffic. Easing off lets it finish and get back over.
When a truck passes you, you can help the driver by keeping to the far side of your lane and reducing your speed slightly.
On the test
You have just passed a truck and its driver blinks the headlights. What does it mean?
You are clear to pull back in front. The truck driver can see the gap better than you can. The flash tells you there is room, but still check for its front in your mirror. Tennessee Comprehensive Driver License Manual, p.109: “If the truck or bus driver blink their vehicle headlights after you pass, it’s a signal that you are cleared to pull back in front of their vehicle.”
How this works
Most practice tests hand you a bank of questions and leave the manual somewhere else. This one puts them together.
You read one law and the reason behind it, then answer a question on that law while it is still fresh. Get it right and you move on; get it wrong and you have found the gap while it is cheap to fix, not on the morning of the exam.
Learning one rule at a time, and proving it immediately, is what turns a manual you skimmed into something you actually know — and it makes studying feel like getting somewhere rather than like waiting to find out.
