Road warning signs pictured — Tennessee Permit Test
Road warning signs pictured on the Tennessee permit test — 6 rules, each with the reason behind it and a question on it while it is fresh.
The rules
This sign tells you that you are approaching a crossroad.
Cars can come at you from both sides at a crossroad. Knowing it is coming lets you slow and look left and right.
This sign tells you it is a crossroad.
This sign tells you to be prepared for a rather sharp turn to the left.
A sharp turn taken at full speed can throw your car off the road. The sign gives you time to slow before it.
This sign tells you to be prepared for a rather sharp turn to the left.
This sign tells you to be prepared for a curve to the right.
A curve hides what is beyond it. Entering too fast can push you across the center line into oncoming cars.
Curve Sign: This sign tells you that you must be prepared for a curve to the right.
This sign warns that a lane is ending and drivers should merge left, signaling first.
Two lanes are about to become one. Without a signal, the driver beside you does not know you are coming over.
This sign is warning of the lane ending and that drivers should merge left.
This sign warns that traffic may blend into your lane; after checking behind you, move to the other lane if possible to give the merging driver room.
A car coming up the ramp needs space to join. Moving over keeps it from being squeezed into your side.
After checking to your rear, you should move into the other lane, if possible, to allow the merging motorist a clear path.
This sign tells you the bridge is narrow and passing cars may need to slow down.
On a narrow bridge two cars pass with little room. Going in fast leaves no space to correct a drift.
This sign tells you that the bridge is narrow and may require passing cars to reduce speeds.
On the test
What does this sign mean?
A crossroad is ahead. Cars can come at you from both sides at a crossroad. Knowing it is coming lets you slow and look left and right. Tennessee Comprehensive Driver License Manual, p.36: “This sign tells you it is a crossroad.”
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.
