Detailed explanation-1: -People with poor depth perception often have difficulty judging when to start slowing down for a stop sign. They also have great difficulty deciding when to pull out into the intersection because it is hard to judge how quickly other cars are approaching.
Detailed explanation-2: -Alcohol blunts alertness and reduces motor co-ordination. People who drive after using alcohol can’t react as quickly when they need to. Their vision is affected, and may be blurred or doubled. Alcohol alters depth perception, making it hard to tell whether other vehicles, pedestrians or objects are close or far away.
Detailed explanation-3: -Marijuana can impair judgment, memory, depth perception, and coordination. A person who uses marijuana may think that the effects of the drug have worn off after a few hours.
