Driving with a hangover is just as dangerous as being drunk, Ford points out

For more than two decades, Ford has promoted the Driving Skills for Life program, an initiative aimed at training newly qualified drivers. The objective of the training is to complement traditional training, focusing on critical skills such as hazard recognition, vehicle control and space and speed management, in addition to warning about the risks of driving under the influence of substances or distractions.

One of the recent differentials of the program, as highlighted in a report by the Today program, is the focus on the risks of driving in a hangover state. Although alcohol may have already been eliminated from the bloodstream, the residual effects on the body directly impact road safety.

Cognitive and physiological impacts

According to the data presented by the program, the hangover state can compromise cognitive functions in a similar way to drunkenness. Sleep deprivation and neurochemical changes resulting from excessive alcohol consumption lead to reduced reaction time and fatigue, factors that make it difficult to make quick decisions in emergency situations.

Hands-on simulation with the “hangover suit”

To demonstrate these hazards in a controlled manner, Ford uses specific simulation equipment. The costume consists of:

  • Weights and vests: They alter balance and body perception.
  • Special glasses: Simulate sensitivity to light and visual distortions.
  • Headphones: They reproduce the perception of headache and sound discomfort.

During closed-loop tests, the program demonstrated that obstacle avoidance maneuvers and sudden lane changes become significantly more difficult. In practical demonstrations, drivers who performed accurately under normal conditions lost control of the vehicle and left the track when using the simulator, even at reduced speeds, such as 48 km/h.

The initiative reinforces that safety behind the wheel does not depend only on the absence of alcohol in the blood at the time of driving, but also on the driver’s full physical and mental state.
