Even a small amount of alcohol affects your judgement, alertness and reaction times. To find out how, follow the instructions at the beginning of each task to complete each driving assessment.

Staying sober behind the wheel assures your awareness is high and reactions are quick. You’re about to find out how.

Extraocular MusclesWhy can’t you see?

Alcohol causes double vision as it slows down the brain, affecting control of the extraocular muscles (muscles in your eye), which are responsible for eye movement. Your eyes still work, but find it harder to focus on an object.

Alcohol also deteriorates the tear-film - the thin layer of liquid that protects the eyes. This can cause "halos" from street lights and other visual disturbances, especially at night. The combination of double vision and visual distractions can severely impact your ability to focus on the road and spot hazards before it's too late.

Pupil DilationWhy do lights seem so bright?

Pupils need to open and contract to react to changes in light, as shown in the diagram. Alcohol makes these reactions slower than normal.

This means drink drivers are more likely to be dazzled by oncoming headlights or other sudden sources of bright light, increasing their risk of accidents.

Reticular activating systemWhy can’t you stay awake?

The reticular activating system (RAS) is the part of the brain that controls sleep and wakefulness.

Alcohol affects the RAS, making drivers feel drowsy. This response to alcohol is actually your body’s way of protecting you - it causes you to pass out before you drink enough to shut down the part of the brain (medulla) that controls vital functions like breathing and heart rate. But when you're behind the wheel, drowsiness can be deadly.

Frontal lobe & ventral striatumWhy do you feel invincible?

Alcohol affects the frontal lobe of your brain, which controls judgement, emotions and behaviour. People who drink drive may be prone to aggressive driving or making bad decisions.

The ventral striatum is the reward centre of the brain. Alcohol can increase the presence of the "happy" chemical dopamine here, causing a feeling of wellbeing which can impair judgement about your ability to drive while under the influence.

Cerebellum & Primary Motor CortexWhy are my reactions so slow?

The cerebellum and primary motor cortex are the parts of the brain that control movement, balance and coordination. When affected by alcohol, reactions become slower and movements and coordination are impaired.

The sedative effects of the neurotransmitter gamma-aminobutyric acid (GABA) are increased by alcohol, making you feel more calm and relaxed. Alcohol also lowers the amount of glutamate produced. Glutamate is a neurotransmitter that increases brain activity, so when under the influence of alcohol the lack of glutamate causes the brain's communication networks to slow down. The combined effects of the increased GABA and lower amounts of Glutamate are slow movement, slurred speech and less control, which are all dangerous when behind the wheel.

Verdict...

Smashed

No matter how capable you feel, there's no cheating your body when it comes to alcohol. You're playing with your life and other people's if you drive under the influence.

The Outcome

Driving requires concentration and attention but, as you've seen, that’s not possible when you've been drinking. Alcohol impairs your eye movement and reactions to light, making it harder to focus on the road. It makes you drowsy and sluggish, making it easier for sudden hazards to surprise you. It can also affect your personality, making you less patient and more aggressive on the road.

Perhaps most dangerously of all, the feeling of well-being alcohol causes can make you think you’re OK to drive – and impair your ability to recognise all of the other physiological effects alcohol has on your body.

Final Thought...

Alcohol is a factor in roughly ¼ of all road deaths, as well as thousands of accidents and serious injuries. Budget Direct is committed to looking after its customers so please don’t drink and drive.
