What is typically a major cause of traffic crashes?

Exceeding the speed limit

Not communicating vehicle intentions

Not communicating vehicle intentions is indeed a major cause of traffic crashes. Effective communication on the road is essential for ensuring the safety of all users. When drivers fail to signal their intentions—such as turning, changing lanes, or merging—they can create confusion for other drivers and pedestrians, which can lead to dangerous situations and collisions.

Clear communication includes the use of turn signals, brake lights, and even eye contact with other road users when necessary. Drivers who neglect to signal may cause other motorists to misinterpret their movements, resulting in unexpected lane changes or turns that can lead to accidents. Therefore, consistently communicating intentions is fundamental to maintaining safety and reducing the likelihood of traffic incidents.
