In urban areas, drivers must come to a complete stop when moving out of an alley, building, private road or driveway and before entering the sidewalk area. If there is no sidewalk, stop at a point nearest the street or roadway where there is a view of approaching traffic. After stopping, yield the right of way to pedestrians and all vehicles.
#8. You are driving on a four-lane highway. From which lane should you make a right turn?
When approaching an intersection to make a right turn, stay as far to the right as possible. Make the turn close to the right curb.
If there are double turning lanes on a road with multiple lanes, they are indicated by regulatory signs and lane markings.
#9. How can you avoid letting your cell phone distract you while driving?
Minimize distractions. Focus on safe driving practices. If your cell phone rings, do not answer it. Let the call go to voicemail, if you have this feature.

When following a large vehicle, stay out of its blind spots. Position your vehicle so the driver can see it in the side mirrors.

A flashing red signal light means stop. After stopping, you may proceed when it is safe. Observe the right-of-way rules.
A flashing red signal is used at intersections when a stop sign alone is hard to see or where additional emphasis on the stop sign is needed. They also are used at railroad crossings to warn of approaching trains. Stop. Never try to beat a train to a crossing.
#16. What should you do when following a motorcycle on gravel roads?
A driver should allow a greater following distance when behind a motorcycle so the motorcyclist has enough time to maneuver in an emergency. Motorcycles react differently to traffic, weather and road conditions than cars. Riders may respond in ways a vehicle driver does not expect. Wet or icy roads impair a motorcyclist’s ability to brake and maneuver. Wind gusts, both natural and those created by large passing vehicles, can move a motorcycle across an entire lane if the rider is not prepared. Potholes or railroad tracks often require motorcyclists to change positions within their lane. Gravel roads decrease traction and may cause a rider to slow down or brake where a car would not.
#17. If your car starts to skid, what is the most common cause?
Unsafe speed is the most common cause of skidding accidents.
#18. Are you allowed to drive faster than the speed limit when overtaking another vehicle?
You may NOT exceed the speed limit when passing. Obey all regulatory and warning signs.
#19. On this road with white lines, traffic flows in one direction only.
White lines mark traffic lanes going in the one (same) direction.
#20. This type of barricade is used:
The diagonal stripes on the barricade or vertical panel guide the driver towards the direction to which the traffic is to pass. Stripes sloping downward to the right mean the driver should bear to the right. Stripes sloping downward to the left mean bear to the left.

No more than one passenger under 20 years for the first 12 months.
For the first 12 months or until you turn 18, whichever occurs first, the number of passengers is limited to one person under 20 years. A sibling, stepsibling, child, or stepchild of the driver is not counted towards this limit.
After 12 months or when you turn 18, the number of passengers is limited to one in the front seat and the number of safety belts in the back seat.
No use of cellphones.
All cellphone/wireless use while driving, including a hands-free device, is prohibited if you are under 19 years and not in an emergency.

Two moving violation convictions within a 24-month period will result in a minimum one-month license suspension.
