Final answer:
It is true that reducing speed and glancing left and right when approaching an intersection is a key safety practice for drivers. This enables them to react to hazards and be aware of other vehicles, including those that may disregard speed limits.
Step-by-step explanation:
When approaching an intersection, it is true that it's important to reduce your speed and glance to the left and right. This practice is part of defensive driving and is crucial for ensuring safety on the road. Reducing speed allows you more time to react to any potential hazards, and looking both ways ensures that you are aware of all the traffic that may cross your path, including vehicles that may be speeding through the intersection regardless of the posted speed limit. A traffic signal can influence driving behavior by necessitating that vehicles slow down, but in their absence, the responsibility falls to each driver to navigate intersections with caution.
For example, let's say you are approaching an intersection and you do not reduce your speed or check for oncoming traffic. If a vehicle is approaching from the left or right and you are unaware of it, a collision could occur.
Remember, always approach intersections with caution and follow traffic rules and signals to ensure your safety and the safety of others.
