True

Explanation:

Driving is a complex task, and it calls for someone to pay full attention and to be stress free because one needs to be calm and fully focused on this task.

When one is experiencing some level of heightened emotions for example stress it is likely that they won't concentrate on the road or driving as they will be distracted by these stressors that are haunting their mind. This means they won't focus on any potential hazards or any signs on the road because their mind is somewhere else trying to resolve the stressful situation.

Researchers have discovered that stressed drivers are likely to overspeed and take unnecessary risks that may lead to accidents.
