Reaction times
Many factors can impact on your reaction times.
Alcohol
Drinking only a small amount of alcohol can seriously effect our ability to react. Drivers with 50–80 mg blood alcohol content (under the legal limit) are around 2.5 times more likely to have an accident.
Tiredness
Tiredness is a factor in around 10% of accidents (20% on motorways). If you are tired, opening the window, turning up music, drinking coffee or taking a short nap may work for a short time.
Using mobile phones and talking to passengers
These both take our concentration away from the road. Using a mobile phone also means we are in less control of our vehicle. When talking to passengers we often take our eyes off the road and take longer to spot hazards.
Driving experience
Inexperience means it takes longer to identify something as being a hazard and longer to decide what to do about it.
Lack of concentration
It can be easy, particularly on long or familiar journeys and motorway driving, to lose concentration and drive on auto-pilot.
The weather
Rain, snow, fog, bright sunlight and other weather conditions will alter our ability to see, increasing the time it will take us to react to a hazard.
Other distractions
- Eating while driving
- Using your in-car stereo
- Map reading
- Looking at the scenery
- Smoking
- Finding parking
Often more than one of these factors is present.
