Correct answer: Warning of a hazard or change in road conditions
Yellow diamond-shaped signs are warning signs that alert drivers to potential hazards.
Diamond-shaped signs with a yellow background alert drivers to upcoming hazards such as sharp curves, steep grades, merging traffic, or slippery roads, placed well in advance to allow speed adjustment.
Question 3: A sign showing a red circle with a white horizontal bar means:
- Stop ahead
- No entry for all vehicles (Correct answer)

- No parking
Correct answer: No entry for all vehicles
The red circle with a white horizontal bar is the universal No Entry sign.
The No Entry sign prohibits all vehicles from entering the road or area ahead. It is commonly placed at one-way street exits and restricted areas. Violating this sign can cause head-on collisions.

- Speed limit information
- Direction and distance information to cities or exits (Correct answer)
- Warning about road conditions

Correct answer: Direction and distance information to cities or exits
Green rectangular signs on highways are guide signs providing directional information.
Green guide signs on highways display destination names, exit numbers, distances in kilometers, and lane assignments for exits, helping drivers plan lane changes and navigate.
Question 5: A triangular sign with a red border showing two arrows facing each other indicates:
- Divided highway ahead
- Two-way traffic ahead (Correct answer)
- Merge lanes ahead
- Road narrows ahead
Correct answer: Two-way traffic ahead
This warning sign alerts drivers that they are about to enter a road with two-way traffic.
The two-way traffic warning sign is typically placed where a one-way road transitions to two-way traffic, warning drivers to expect oncoming traffic and stay in their proper lane.
