1. That statement is True
Both motorcyclist and automobiles drivers are required to follow the same street signs and traffic light that exist on the road. They both also expected to bring driving license and banned from driving if they are having the same amount of blood alcohol level.
2. I believe the answer is: C. Rush hour traffic
Rush hour traffic refers to the time period when most of drivers choose to live their house and enter the road (typically near the time of work hours start and 8 - 9 a.m and by the end of work hours end at 5-6pm). Getting on these hours would make you stuck on the road for a really long time and increase your stress level.
3. I believe the answer is: A. 3
The 3 feet distance is necessary to give the drivers' vehicles enough time when the brakes it hit until the vehicles are fully stop, because if both automobiles and cyclist are colliding, the cyclist would most likely obtain more sever injuries.
4. I believe the answer is: Six to eight hours
Just like any other activities, driving also require some level of brain activity that help use concentrate/focus on the job. When our brain is made to do a same repetitive work for more than six hours, our concentration level would dropped. On the road, this would increase the chance of accidents.
