Every year thousands of car accidents happen due to road fatigue. Drivers either don't recognize the signs of fatigue or they choose to ignore them. While there are no rules for private transportation, common sense is often a key factor. The maximum number of hours to safely drive per day varies from driver to driver and situation to situation.
Professional drivers are allowed by law to drive 10 hours per day. Their experience being on the road every day makes them better equipped to drive long distances than other drivers. Taxi drivers, public transportation drivers and delivery drivers should not equate their abilities with truck drivers. Highway driving is not the same as city driving.
A few facts should be taken into consideration when it comes to social driving.
Recognize the signs
Learn to recognize the signs that you are in danger of falling asleep.
Prepare yourself before hitting the road.
While professional drivers have to adhere to legally-defined maximums for hour driven per day, you don't. You have to use common sense to know when it's time to take a break to avoid having an accident.
