1. Under Missouri's graduated license, intermediate drivers and their passengers must:

2. You are going the opposite direction from a stopped school bus with red lights flashing, on a highway with four lanes. What does Missouri law require of you?
- A. Stop until the red lights turn off
- B. Stop, then pass at 10 mph or less
- C. Stop only if children are visible
- D. You are not required to stop (correct)
Why: On a highway with four or more lanes, Missouri does not require drivers going the opposite direction to stop for a school bus. Traffic following the bus must still stop. Watch for children anyway.

3. In most states, which left turn may you make on a steady red light after a full stop, if no sign forbids it?
- A. From a two-way street onto another two-way street
- B. From any street when no oncoming car is in sight
- C. From a two-way street into a store's driveway
- D. From a one-way street onto another one-way street (correct)
Why: Most states allow a left turn on red from a one-way street onto another one-way street that carries traffic to the left. You must stop fully and yield to pedestrians and traffic first.
4. If your vehicle's engine catches fire, you should:
- A. Open the hood to reach the fire quickly
- B. Stop, shut off the engine, and get everyone away (correct)
- C. Drive on to the nearest fire station
- D. Stay in the car with the windows up until help comes
Why: If your engine catches fire, pull off the road, shut off the engine, and get all occupants out and well away from the vehicle. Do NOT open the hood - adding oxygen can intensify the fire. Call 911.
5. You are behind a school bus on a four-lane highway with a raised median. The bus stops with red lights flashing and its stop arm out. What must you do?
- A. Pass slowly in the left lane
- B. Stop - traffic behind the bus must stop (correct)
- C. Keep going because the road is divided
- D. Stop only if you see children outside
Why: A divided highway may excuse traffic on the opposite side, but never drivers going the same way as the bus. Stay stopped until the red lights stop flashing and the stop arm is pulled in.
6. What is the danger zone around a large truck where the truck driver cannot see you?
- A. Only behind the trailer and on its right
- B. In front, behind, and along both sides (correct)
- C. Only beside the cab on the driver's side
- D. Large trucks have no blind spots with modern mirrors
Why: Large trucks have significant blind spots (no-zones): directly in front (20 feet), directly behind (30 feet), to the right (2 lanes wide), and to the left (1 lane). If you cannot see the driver's face in their mirror, they cannot see you.
