Final answer:
To avoid accidents, it is crucial to adjust the speed of a vehicle to the conditions and adhere to the ideal speed and posted speed limits, especially in areas with increased safety concerns like school zones.
Step-by-step explanation:
The question alludes to the concept that speed must be adjusted to conditions to avoid accidents. Indeed, driving at the ideal speed means operating the vehicle at the maximum safe speed in which one can still maintain control, particularly when turning on a curve without relying on excess friction between the tire and the road.
Observing the speed limit is critical because vehicles typically require a greater stopping distance at higher speeds, and this is further extended if the road conditions are poor.
Specifically, vehicles traveling through intersections without adhering to the posted speed limit pose a hazard, and traffic control measures such as traffic signals are often employed to force vehicles to slow down for safety reasons. For example, reduced speed zones near schools are implemented because vehicles traveling at high speeds cannot stop quickly, increasing the risk of accidents.
