Final answer:
The correct distance to park from the nearest rail of a railway crossing is 5 meters. Following this law ensures road safety near train tracks. It's also important to understand safe distances when crossing the street with traffic.
Step-by-step explanation:
You should park within 5 meters of the nearest rail of a railway crossing unless otherwise posted. The correct answer is A) 5 meters. Parking too close to a railway crossing is dangerous and can be illegal because it might obstruct the view of the trains for other road users and can also cause traffic congestion. It's important to follow these rules to ensure safety for all vehicles and pedestrians near train tracks.
To provide more context, understanding distance and time can be crucial for safety on the roads. For instance, if a car is traveling at the speed limit of 60 km/hr, one has to measure an adequate distance to cross safely. Given that an average car length is 3.5 meters, and you need to walk at least 4 meters to cross in front of a car safely, you must calculate how far away a car must be to cross the road without risk.
