Railroad Crossing Rules for Truck Drivers
Most trucks must slow down and be ready to stop at a railroad crossing (49 CFR 392.11). A bus with passengers, a truck that must carry certain hazmat placards, and a cargo tank used for hazmat must stop 15 to 50 feet from the tracks, look and listen, and cross without shifting gears (49 CFR 392.10). Every driver needs room to clear the tracks (49 CFR 392.12). A conviction can disqualify a CDL holder for at least 60 days.

Key Points
- These drivers must stop at every railroad crossing: a bus carrying passengers, any truck with chlorine, a truck that must carry placards for listed hazmat, and any cargo tank used for hazmat, loaded or empty (49 CFR 392.10(a))
- The stop must be within 50 feet of the tracks and not closer than 15 feet. Look and listen both ways, then cross in a gear that lets you finish the crossing. Do not shift gears on the tracks (49 CFR 392.10(a))
- A stop is not needed at some crossings: streetcar or industrial switching tracks in a business district, where an officer or flagman waves you on, at a green light under local law, at an abandoned crossing marked as such, or at an "Exempt" crossing sign (49 CFR 392.10(b))
- Every other commercial motor vehicle must slow so it can stop before the nearest rail, and may cross only after taking care to see that the way is clear (49 CFR 392.11)
- No driver may drive onto a crossing without room to drive all the way through without stopping (49 CFR 392.12)
- A CDL holder convicted of a crossing offense is disqualified for no less than 60 days for a first offense, 120 days for a second in 3 years, and 1 year for a third (49 CFR 383.51(d))
- An employer may not let a driver break a federal, state or local law about railroad crossings (49 CFR 383.37(e))
CDL disqualification for a railroad crossing conviction (49 CFR 383.51, Table 3)
| What the driver did | First conviction | Second in 3 years | Third in 3 years | |
|---|---|---|---|---|

| The driver does not obey a traffic control device or the directions of an enforcement official at the crossing | At least 60 days | At least 120 days | At least 1 year | |
| The driver cannot get across because the truck's undercarriage does not clear the crossing | At least 60 days | At least 120 days | At least 1 year |
Which trucks must stop at every railroad crossing?
Four groups must stop every time (49 CFR 392.10(a)). The first is every bus carrying passengers. The second is any commercial motor vehicle carrying any amount of chlorine. The third is any vehicle that must be marked or placarded for one of the hazmat classes the rule lists. Those are Divisions 1.1, 1.2, 1.3 and 1.4 (explosives), 2.1, 2.2 and 2.3 (gases), 4.1, 4.3, 5.1, 5.2 and 6.1, and Classes 3, 7 and 8. The fourth is every cargo tank motor vehicle used to carry any hazardous material, whether loaded or empty. A cargo tank carrying a load that is above its flashpoint when loaded must stop too, and so must a cargo tank hauling under a hazmat exemption. The rule does not name Divisions 1.5, 1.6, 4.2 or 6.2, or Class 9. An ordinary dry van or flatbed does not have to stop under this rule, but state law may ask for more (49 CFR 392.2).
How do you make the required stop?
Stop the vehicle within 50 feet of the tracks, and not closer than 15 feet. Then listen and look in each direction along the tracks for a train, and make sure no train is coming. When it is safe, drive across in a gear that lets you finish the crossing without changing gears. You must not shift gears while you cross the tracks (49 CFR 392.10(a)). Pick your gear before you reach the tracks.
When is a stop not required?
A truck that must normally stop does not have to stop at five kinds of crossing (49 CFR 392.10(b)). They are a streetcar crossing, or railroad tracks used only for industrial switching, inside a business district. They are also a crossing where a police officer or crossing flagman directs traffic to go, a crossing with a working highway signal showing green that under local law lets a vehicle cross without slowing or stopping, and an abandoned crossing with a sign saying the line is abandoned. The last is an industrial or spur line crossing with a sign reading "Exempt." Those signs may be put up only by or with the consent of the state or local authority. A stop is still smart whenever you cannot see that the way is clear.
What must the other trucks do at a crossing?
Every commercial motor vehicle that is not on the stop list must still be slowed on approach. It must be driven at a speed that lets it stop before the nearest rail, and it may not go onto or over the crossing until the driver has taken due care to see that the way is clear (49 CFR 392.11). Most dry vans, flatbeds and reefers fall here. The rule sets no number of feet or miles per hour. The test is whether you can stop short of the first rail.
What is the rule about having room to clear the tracks?
No driver of a commercial motor vehicle may drive onto a highway-rail grade crossing without having enough space to drive completely through the crossing without stopping (49 CFR 392.12). In heavy traffic, wait before the tracks until the vehicle ahead has cleared the far side. A long combination needs a long gap on the far side. This rule applies to every driver, including drivers who are not required to stop at a crossing.
What happens to a CDL after a railroad crossing violation?
A driver who is convicted of a crossing offense in a CMV is disqualified from driving a CMV (49 CFR 383.51(d)). The table above lists six offenses. For each one, the period is no less than 60 days for a first conviction. A second conviction of any mix of these offenses in a separate incident within 3 years brings no less than 120 days. A third or later brings no less than 1 year. The offense can be a violation of a federal, state or local law. An employer may not allow a driver to violate a crossing law (49 CFR 383.37(e)), and may not use a driver during a disqualification (49 CFR 383.37(b)).
What do you do if your truck is stuck on the tracks or the signals fail?
Federal rules require a railroad to run a toll-free phone line for reports of a disabled vehicle or another obstruction on the track, a warning system that is not working, and anything else unsafe at a crossing (49 CFR 234.303(c)). The number is posted at the crossing on a blue and white sign. It must show the phone number, what the sign is for, and the U.S. DOT National Crossing Inventory number that names the crossing (49 CFR 234.309). Call the number, say the crossing number and what is wrong. If anyone is in danger, call 911 as well.

Frequently Asked Questions
Do semi trucks have to stop at railroad crossings?+
Not under federal rules, unless the truck is on the stop list. A semi that does not carry placarded hazmat, and is not a cargo tank used for hazmat, must slow so it can stop before the nearest rail and cross only when the way is clear (49 CFR 392.10 and 392.11). A state may ask for more, so follow local law (49 CFR 392.2).
Which vehicles must stop at all railroad crossings?+
Buses carrying passengers, vehicles with any amount of chlorine, vehicles that must be placarded for the hazmat classes the rule lists, and cargo tank motor vehicles used for hazmat, loaded or empty (49 CFR 392.10(a)).
How far from a railroad crossing must a CDL driver stop?+
Within 50 feet of the tracks and not closer than 15 feet. Then look and listen in each direction for a train (49 CFR 392.10(a)).
Do hazmat trucks have to stop at railroad crossings?+
Yes, if the truck must be placarded for one of the classes in 49 CFR 392.10(a)(3). Divisions 1.1 to 1.4, 2.1, 2.2, 2.3, 4.1, 4.3, 5.1, 5.2 and 6.1, and Classes 3, 7 and 8 are listed. Check the rule for your load.
Do tanker trucks have to stop at railroad crossings?+
A cargo tank used to carry any hazardous material must stop, whether it is loaded or empty (49 CFR 392.10(a)(4)). A tank that carries only non-hazardous goods does not fall under that item.
Can you shift gears while crossing railroad tracks?+
No. Cross in a gear that lets you finish the crossing without changing gears, and do not shift on the tracks (49 CFR 392.10(a)).
Can a hazmat truck skip the stop at a green light?+
A stop is not needed at a crossing controlled by a working highway signal showing green that, under local law, lets a vehicle cross without slowing or stopping (49 CFR 392.10(b)(3)). It is also not needed where an officer or flagman waves you on.
What does an Exempt sign at a railroad crossing mean?+
At an industrial or spur line crossing marked with a sign reading "Exempt," a truck that would normally stop does not have to (49 CFR 392.10(b)(5)). Only the state or local authority, or someone with its consent, may put those signs up.
What happens if I do not stop at a railroad crossing?+
A conviction in a CMV can disqualify a CDL holder for no less than 60 days for a first offense, no less than 120 days for a second within 3 years, and no less than 1 year for a third (49 CFR 383.51(d)). States set their own penalties, and a carrier may not let a driver break a crossing law (49 CFR 383.37(e)).
What should I do if my truck gets stuck on railroad tracks?+
Look for the blue and white sign at the crossing and call the phone number on it. Give the U.S. DOT crossing number shown on the sign and say what is wrong. The railroad must keep a line for reports of a disabled vehicle on the track (49 CFR 234.303 and 234.309). If anyone is in danger, call 911 as well.
