Making quick decisions depends on their ability to quickly recognize risks on the road.

• If the driver is distracted, they will be unaware of what is happening on the road.
• If the driver is impaired, their brain will not register a risk even if they see it several meters beforehand.
• When under the influence of drugs or alcohol, the driver's risk perception becomes very poor.

The driver must ensure they are not distracted and are fit to drive to ensure their reaction times are quick and practical.

Increasing the driver's following distance also gives them more time to decide and safely and effectively execute it.
