What must you do at a white X-shaped railroad crossbuck sign?: Yield to any train; A crossbuck works like a yield sign for trains. Slow down, look and listen both ways, and stop if a train is coming. Trains always have the right-of-way. Source: MUTCD 11th Ed., NY Driver's Manual, Florida Driver Handbook, Texas Driver Handbook.
A sign below a railroad crossbuck shows a number. What does it tell you?: How many tracks you will cross; When a crossing has more than one track, a plaque below the crossbuck shows the number of tracks. After one train passes, another may be coming on a different track. Source: MUTCD 11th Ed., NY Driver's Manual, Florida Driver Handbook, Texas Driver Handbook.
Red lights start flashing at a railroad crossing. What must you do?: Stop and wait until they stop; Flashing red lights at a crossing mean a train is coming. Stop before the tracks and stay stopped until the train passes and the lights stop flashing, then cross only when it is clear. Source: Florida Driver Handbook, Texas Driver Handbook, MUTCD 11th Ed..
The railroad crossing gate is down and no train is in sight. What should you do?: Stay stopped until it rises; Never drive around or under a lowered gate. Wait until the gate goes up and the lights stop flashing; a train may be closer or faster than it looks. Source: Florida Driver Handbook, Texas Driver Handbook, NY Driver's Manual.
Before crossing railroad tracks in heavy traffic, what should you make sure of?: There is room on the other side; Only start across if your whole vehicle can clear the tracks. Stopping on the tracks with traffic backed up can trap you there. Source: Florida Driver Handbook, Texas Driver Handbook, NY Driver's Manual.
Your car stalls on railroad tracks and a train is coming. What should you do?: Get everyone out and away; Get everyone out at once and move well away from the tracks. Then call the number on the blue emergency sign or 911. A car can be replaced; people cannot. Source: NY Driver's Manual, Florida Driver Handbook, Texas Driver Handbook.
What does an orange triangle with a red border on the back of a vehicle mean?: A slow-moving vehicle; The slow-moving vehicle emblem marks farm equipment, road machinery and animal-drawn vehicles that travel at about 25 mph or less. Slow down early and pass only when it is safe and legal. Source: NY Driver's Manual, Florida Driver Handbook, Texas Driver Handbook.
A yellow sign showing a speed is posted under a curve warning sign. What is it?: Advisory speed for the curve; The yellow advisory speed plaque shows the recommended speed for the curve or condition ahead. It is advice set by traffic engineers, not a promise that the speed is safe: adjust to conditions and slow down more in rain, snow, darkness or heavy traffic. Source: Florida Driver Handbook, Texas Driver Handbook, NY Driver's Manual, MUTCD 11th Ed..
What does a yellow diamond sign showing a traffic light mean?: Traffic signal ahead; This warning sign says there is a traffic signal at the intersection ahead, often where it is hard to see. Slow down and be ready to stop. Source: Florida Driver Handbook, Texas Driver Handbook, MUTCD 11th Ed..
What does a Low Clearance sign with a height on it warn you about?: Limited height under a structure; The sign shows the height under a bridge, overpass or tunnel. Do not enter if your vehicle or load is taller than the height shown. Source: Florida Driver Handbook, Texas Driver Handbook, MUTCD 11th Ed..
What does a yellow diamond sign showing a truck on a slope mean?: Steep downhill grade ahead; This hill sign warns of a steep downgrade. Slow down and shift to a lower gear to help control your speed instead of riding the brakes. Source: Florida Driver Handbook, Texas Driver Handbook, MUTCD 11th Ed..
What does a Two-Way Traffic sign (two arrows pointing opposite ways) warn you about?: Oncoming traffic shares the road; The road ahead changes to two-way traffic, or you are on a two-way road. Keep right and expect oncoming vehicles. Source: Florida Driver Handbook, Texas Driver Handbook, MUTCD 11th Ed..

What does a Divided Highway Ends sign warn you about?

The median ends; traffic is two-way

Stay to the right of the traffic island, median or obstruction ahead. Source: Florida Driver Handbook, MUTCD 11th Ed..
What does a No Turn on Red sign mean?

Wait for green to turn

A work zone flagger turns the paddle to show SLOW. What should you do?

Proceed slowly with caution

Flaggers have the same authority as a sign. SLOW means move ahead slowly and watch for workers, equipment and oncoming traffic. STOP means stop. Source: NY Driver's Manual, Texas Driver Handbook, Florida Driver Handbook.
How are Interstate highways numbered?

Odd north-south, even east-west

Interstates that run north and south have odd numbers; those that run east and west have even numbers. Source: FHWA, Florida Driver Handbook.
Under the national MUTCD standard, what are freeway exit numbers based on?

The nearest mile marker

The national standard numbers freeway exits by the milepost (reference location), so the exit number tells you roughly how far you are from the start of the route in that state. Source: MUTCD 11th Ed., Florida Driver Handbook.
A sign shows two roads joining, with an extra lane added. What does it mean for you?

A lane is added; no need to merge

An Added Lane sign means the joining road gets its own new lane. You do not have to merge, but watch for traffic in the new lane. Source: Texas Driver Handbook, Florida Driver Handbook, MUTCD 11th Ed..
What should you do at a yellow diamond sign showing a bicycle?

Watch for bicyclists

The bicycle warning sign means people on bikes often use or cross the road here. Slow down and give them room. Source: Florida Driver Handbook, MUTCD 11th Ed..
