Explanation:

• Question 16: Sleepiness - related crashes are often serious as the driver's reaction time is impaired. Also, high - speed roads are more likely to be involved as the driver may drift off without proper awareness. So both B (The crash is likely to be serious) and C (The crash occurs on a high - speed road) are correct.
• Question 17: Marijuana contains THC (tetrahydrocannabinol) which binds to cannabinoid receptors in the brain. This affects neurotransmitter release, thereby altering perception (such as visual and auditory perception), emotions, and also impairs motor coordination. So the statement is True.
• Question 18: The three - second rule is a common rule of thumb in driving. It states that a driver should stay at least three seconds behind the vehicle in front in good weather and clear visibility. This allows for a safe stopping distance.
• Question 19: According to the National Highway Traffic Safety Administration (NHTSA) data, in 2022, there were 14,263 fatalities in alcohol - related crashes in the United States. So the statement is True.
• Question 20: Motor vehicle crashes are indeed the leading cause of death for 15 - 20 year - olds in the United States. This age group is more likely to engage in risky driving behaviors (such as speeding, distracted driving, and driving under the influence) due to inexperience and a sense of invincibility.
