To determine how far a vehicle must stop from the draw of a drawbridge when there is no traffic light or attendant, we need to consider general traffic laws that apply in such situations.
Here are the given options:
a. 5 feet
b. 10 yards
c. 50 feet
d. 100 feet
Step-by-Step Elimination Process:
1. Option (a) 5 feet:
- Stopping only 5 feet from a drawbridge seems much too close and would not provide sufficient safety.
2. Option (b) 10 yards:
- To convert yards to feet: 1 yard = 3 feet, so 10 yards = 10 x 3 = 30 feet.
- 30 feet is farther than 5 feet but might still be considered too close to the drawbridge for safety.
3. Option (c) 50 feet:
- Stopping 50 feet away seems like a reasonable and safe distance. This allows enough space in case an emergency arises or if the bridge suddenly starts to open.
4. Option (d) 100 feet:
- Stopping 100 feet away, while safe, might be unnecessarily far, especially in urban areas where road space is valuable.
Considering typical safety regulations and the practical need to ensure vehicles are at a safe distance without being excessively far, 50 feet is the most appropriate distance to stop from the draw of a drawbridge when there is no traffic light or attendant present.
So, the correct answer is:
c. 50 feet
