Final answer:
A vehicle should not be parked closer than 15 feet to a fire hydrant, school bus, railroad crossing, and stop sign for safety reasons and to provide clear access for emergency vehicles. Therefore, the correct answer is option b. 15 feet
Step-by-step explanation:
The question relates to the safe and legal parking distance a vehicle must maintain from a fire hydrant, school bus, railroad crossing, and stop sign.
The correct answer is (b) 15ft. Vehicles should not be parked closer than 15 feet to these areas to ensure safety and access, especially in the case of emergency vehicles that may need to use the fire hydrant or have clear pathways at crossings and intersections.
This rule is important for maintaining road safety and ensuring that emergency responders can access the fire hydrant without obstruction.
When it comes to crossing the road, it is essential to judge the distance and speed of oncoming vehicles to determine a safe interval for crossing; typically, more than 28 meters or beyond the length of several parked cars may be considered safe.
Therefore, the correct answer is option b. 15 feet
