TDC - Theoretical Driving Course Traffic Signs and Markings 2 — Questions and Answers
Question 1: What do broken white lane lines on a road indicate?
- No lane changing permitted
- Lane changing is permitted when safe (Correct answer)
- The road is closing ahead
- Reserved bus lane boundary
Correct answer: Lane changing is permitted when safe
Broken white lines separate same-direction lanes and indicate lane changing is permitted.
Broken lines indicate crossing is permitted while solid lines indicate restrictions. Broken white lines separate same-direction traffic. Solid white lines discourage lane changes near intersections.
Question 2: What does a large white triangle painted on the pavement indicate?
- Merge area ahead
- Yield to other traffic (Correct answer)
- Speed bump ahead
- Pedestrian waiting area
Correct answer: Yield to other traffic
A painted triangle (yield marking) indicates drivers must give way to traffic on the intersecting road.
The yield pavement marking supplements the posted yield sign. Drivers must slow down and give way to intersecting traffic. If the way is clear, the driver may proceed without stopping.
Question 3: What is the meaning of zigzag road markings near a pedestrian crossing?
- Speed bump area
- No overtaking and no parking zone near the crossing (Correct answer)
- Slippery when wet
- Bicycle lane markings
Correct answer: No overtaking and no parking zone near the crossing
Zigzag markings near crossings indicate a no-overtaking and no-parking zone for pedestrian visibility.
Zigzag markings prohibit overtaking so a stopped vehicle yielding to pedestrians is not passed by another vehicle that cannot see the pedestrian, and prohibit parking to maintain clear sightlines.
Question 4: What does a green arrow signal on a traffic light indicate?
- All traffic may proceed in any direction
- Traffic may proceed only in the direction of the arrow (Correct answer)
- Turn right on red is permitted
- The light is malfunctioning
Correct answer: Traffic may proceed only in the direction of the arrow
A green arrow allows traffic to move in the arrow's direction as a protected turn phase.
During a green arrow, opposing traffic has a red signal, providing a protected turn. A green arrow alone means only that movement is permitted. With a circular green, both through and turn movements are allowed.
Question 5: What do chevron signs on the side of the road indicate?
- One-way street ahead
- A sharp curve or bend in the direction of the arrows (Correct answer)
- Merge area ahead
- Road construction detour
Correct answer: A sharp curve or bend in the direction of the arrows
Chevron signs are placed on sharp curves to guide drivers through the turn.
Chevron alignment signs help drivers gauge curve sharpness and direction, especially at night. Multiple chevrons are placed along the curve with spacing reflecting its severity. Important on mountain roads.
Question 6: What does a road sign showing a car with curved skid lines on yellow background warn about?
- Racing zone ahead
- Slippery road surface when wet (Correct answer)
- Speed bump ahead
- Road narrowing ahead
Correct answer: Slippery road surface when wet
This warning sign indicates the road surface ahead may become slippery.
Commonly placed on bridges which freeze before roads, downhill slopes with drainage issues, and newly paved roads. Drivers should reduce speed, avoid sudden braking, and increase following distance.
