Final answer:
You should avoid being between a semi-truck and a curb because it's a hazardous position. Assess vehicle speed and distance before crossing a road, and there's no absolute safe distance or number of car-lengths as safety depends on various factors. A freight truck's trailer bouncing slowly tends to indicate it is nearly empty.
Step-by-step explanation:
No, you should not be between a semi-truck and a curb; it's a dangerous position that should be avoided. Being in this space can put you in a truck's blind spot and increase the risk of an accident.
If you see a car driving toward you and it is 28 meters away, you need to assess the speed of the car before deciding if it's safe to walk across the road. As a rule of thumb, a car distance equivalent to 8 car-lengths may give you enough time to cross safely if the car is moving at a slow pace, but it's always best to wait until it's completely safe before crossing.
When crossing multiple lanes, such as when a rabbit tries to cross a freeway, it's crucial that all approaching vehicles are at a sufficient distance to ensure safety. There is no fixed distance or number of car-lengths that can guarantee safety as it depends on various factors such as the speed of the vehicles, the number of lanes, and the crossing speed of the individual.
A freight truck trailer bouncing up and down slowly is more likely to be nearly empty. A heavily loaded trailer would have less give and would not bounce as much because the weight stabilizes it.
