Regulatory signs — Tennessee Permit Test
Regulatory signs on the Tennessee permit test — 9 rules, each with the reason behind it and a question on it while it is fresh.
The rules
On a highway with more than one lane each way, a SLOWER TRAFFIC KEEP RIGHT sign means you must drive in the far right lane unless passing a slower car or turning left.
Slow cars in the left lane force faster drivers to weave around them. That weaving is where crashes start.
It means that you must drive in the extreme right lane unless you want to pass a slower moving car or make a left turn.
Never straddle lanes or drive in the center lane when moving more slowly than the traffic around you.
A slow car in the middle lane blocks both sides. Drivers then pass on the right, where you may not look.
Never straddle lanes or drive in the center lane when moving more slowly than other traffic around you.
No passing zones are set by how far you can see ahead, allowing for hidden hazards such as hills, curves, intersections and driveways.
Over a hill a car may be coming at you that you cannot see. The zone keeps you in your lane until you can.
Passing areas are based on how far you can see ahead.
A triangular no passing zone sign is yellow or orange and is placed on the left side of the roadway.
Most signs are on the right, so drivers miss this one. It sits on the left where you look when you pull out to pass.
These signs are yellow or orange and placed on the left side of the roadway.
Speed control signs show the maximum speed allowed, the minimum speed required, or a change in speed limit.
A posted minimum matters too. A car far slower than the flow on a freeway gets rear-ended.
Speed Control: These signs show the maximum speed allowed, the minimum speed required or a change in speed limit.
A school speed limit sign is used where children are within walking distance of school; it runs on a time clock and flashes yellow lights while showing the limit.
When the lights flash, children are walking to or from school. Driving past at the normal limit can cost a child's life.
This type of sign is controlled by a time clock and flashes yellow lights while illuminating the speed limit.
A sign with a white background and a red circle with a diagonal line means NO to whatever is shown behind the red symbol.
The picture under the slash tells you what is banned. Missing the slash means doing the one thing the sign forbids.
Signs having a white background and a red circle and a line diagonally through them mean “NO” according to what is shown behind the red symbol.
In Tennessee, it is illegal to stand on a roadway to ask for a ride.
Hitchhiking puts a person on foot in the traffic lane. It also puts a driver at risk by stopping for a stranger.
In Tennessee, it is illegal to stand on a roadway to solicit a ride.
The HOV sign marks lanes reserved for buses and vehicles with the minimum number of occupants shown on the sign.
Driving alone in a carpool lane slows the buses and carpools it is meant for, and it can get you a ticket.
This sign (High Occupancy Vehicle) indicates lanes reserved for buses and vehicles with the minimum number of occupants specified on the sign.
On the test
On a multi-lane highway with a SLOWER TRAFFIC KEEP RIGHT sign, where should you drive?
In the far right lane. Slow cars in the left lane force faster drivers to weave around them. That weaving is where crashes start. Tennessee Comprehensive Driver License Manual, p.37: “It means that you must drive in the extreme right lane unless you want to pass a slower moving car or make a left turn.”
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.
What it costs

- Paying opens the rest of the cards, unlimited full-length practice tests, and retests built from exactly the questions you got wrong.
- Every level up to Prepared — 3 tests passed in a row.
- Do the work, fail the real exam, and we refund you.
