Alcohol
Drinking and riding is as common among motorcyclists as drinking and driving is among drivers, but riders are far more likely to be killed or badly hurt in a crash; about 2,500 motorcycles crash on New Jersey roads each year, with 60 or more deaths and nearly 2,000 injuries. p. 203
Alcohol
Nearly half of all motorcycle highway deaths involve alcohol; riding takes a high degree of skill, judgment and balance, all of which alcohol limits. p. 203
Alcohol
Alcohol affects vision, making it hard to see clearly and judge distance, which is hard enough on a motorcycle with normal vision. p. 203
Fatigue
To limit fatigue on a trip, don't ride more than about 300 miles a day, and take frequent rests: stop, get off the motorcycle and drink some water. p. 204
Drugs
If a prescription or over-the-counter drug makes you dizzy or weak, stop and wait until you feel normal; when you ride again, slow down and keep more distance than usual from other vehicles. p. 204
Fatigue
Riding a motorcycle is more tiring than driving other vehicles: on road trips tiredness sets in sooner, and fatigue can hurt your control of the motorcycle much more. p. 204
