In addition, having alcohol in the body while youre driving messes up your distance and speed perception, making you see things farther or closer than they really are, or makes you feel like youre driving the speed limit when youre really speeding.
You need quick decision-making, reflexes, accurate perception, and multitasking skills to drive well and safely. Even one drink can make you an unsafe driver. And remember, driving with any alcohol in your bloodstream or in your car is illegal if youre under the age of 21.
