2. Under a move-over law, what should you do when approaching a stopped emergency vehicle on the roadside?

3. What does a cross-buck sign at a railroad crossing require of you?
Correct answer: Yield the right-of-way to any train or on-track equipment
The cross-buck marks the grade crossing and requires drivers to yield to trains; where multiple tracks exist, a sign below it shows how many.

4. When the red lights at a crossing begin to flash, what must you do?
Correct answer: Stop and yield, because a train is approaching
Flashing red lights warn that a train or other equipment on the tracks is approaching; stop and yield, and where the crossing has several tracks, confirm every one is clear before moving.

5. About how long does a typical tractor-trailer need to clear a single set of tracks?
Correct answer: At least 14 seconds
A typical tractor-trailer takes a minimum of 14 seconds to get across one track, and over 15 seconds across two, so never stop where you could be trapped on the rails.

6. At a crossing equipped with gates, when may you proceed?
Correct answer: Only after the gates are fully up and the lights have stopped flashing
Stay stopped until the gates have gone all the way up and the flashing lights have stopped, then cross only when it is clearly safe.

7. Why do double tracks call for an especially careful look before crossing?
Correct answer: A train on one track can hide a second train on the other
One passing train can conceal another approaching on the second track, so look both ways and be sure no other train is near before you start across.

8. If moving over a lane is unsafe when passing a roadside emergency vehicle, what should you do instead?
Correct answer: Slow down and pass cautiously at a safe speed
When a lane change cannot be done safely, reduce your speed and proceed with caution while keeping a speed appropriate for traffic conditions.

9. What is the rule about trying to beat a train to a crossing?
Correct answer: Never race a train, since judging its speed is extremely difficult
Never try to outrun a train to the crossing; the speed of an approaching train is very hard to judge and misjudging it can be fatal.

10. Before starting across a road that intersects traffic, what must you be sure of?
Correct answer: That you can clear the entire road before oncoming traffic arrives
Given a large vehicle's slow acceleration, confirm you can clear the entire road before traffic arrives; a heavier load needs even more room.

11. Which vehicles are required to stop at railroad advance warning signs?
Correct answer: Passenger-carrying and hazmat-carrying vehicles
The advance warning sign tells all drivers to slow, look, and listen, but buses carrying passengers and vehicles carrying hazardous materials are specifically required to stop.

12. At a passive railroad crossing (no lights or gates), who decides whether it is safe to cross?
Correct answer: The driver, who must search the tracks and judge the clearance
A passive crossing has no control device, so it falls entirely on you to recognize the crossing, look for any train, and decide whether there is room to cross safely.
