Railroad Crossing Lights, Signals and Gates: Driving Safety

Updated Dec. 5, 2019

Many railway crossings around the United States feature traffic lights to warn drivers that a train is approaching. Despite this, railroad crossing accidents still occur and often catastrophic. Understanding how railroad crossing signals work is vital to your safety. Never ignore warning signals or attempt to beat a train through a crossing – you will not win.

Railroad crossing gates and lights

Horizontal red traffic lights are often installed on or near to the crossbuck sign marking the crossing. The lights are usually accompanied by a bell signal. Safety gates may or may not be present at the crossing.

Flashing red traffic lights mean that a train is approaching. Motorists must not attempt to cross railway tracks when a red traffic light or bell signal is active. Stay put, even if the warning light keeps flashing yet no train appears. The Federal Railroad Administration (FRA) implements a minimum warning time of 20 seconds, though many crossings have warning signals which activate 30 to 40 second prior to a train passing through.

Drivers must stop within 50 feet of the railroad crossing and at least 15 feet away from the crossing when warning signals are active (the minimum distance at which drivers must stop may vary from state to state, check your driving handbook for local information). You must also stop if a flagger indicates a train is coming, or if you can see or hear an approaching train.

A lowered safety gate or barrier also indicates that a train is about to move through the crossing.  Like warning lights, the safety gate may be activated a considerable amount of time before the train passes through. NEVER attempt to drive around a closed safety gate – even if you suspect it might be malfunctioning.

Malfunctioning or inoperative railroad signals and safety devices must be reported using the emergency notification system (ENS), as discussed below.

Railroad crossing dangers

Keep in mind that warning lights may be malfunctioning if they are not active! Always conduct a visual check for trains in both directions before moving over a crossing, even if traffic lights indicate that the track is clear.

Warning signals only improve driver safety when drivers themselves follow the rules. According to a report published by the Federal Railroad Administration in 2015, more than 60 percent of train-vehicle collisions happen at crossings which are installed with automatic warning systems. These collisions can be largely attributed to irresponsible driving, such as:

  • A motorist trying to rush over a crossing when a warning signal is active.
  • A motorist moving over a crossing when there is not room for their vehicle on the other side. This often happens when a line of vehicles is using the crossing. If another vehicle closes the gap behind you, you could be blocked in on the railway track.

Emergency notification systems (ENS)

An emergency notification system sign will be posted near the crossbuck sign at practically all railroad crossings. This system is designed to facilitate a rapid response when emergency situations occur at railway crossings, or malfunctioning signals jeopardize public safety. In an emergency, motorists should use the phone number and crossing reference number on the ENS sign to contact the railroad authority in charge of the crossing.

Railroad crossing without signals

As of 2015, 50 percent of railroad crossings on public roads were equipped with flashing warning signal lights. Of that number, 35 percent also had safety gates. Further lights and gates have been installed at crossings around the United States in the past few years, though there are still many crossings with no warning devices at all.

When using a crossing that is not equipped with warning lights or gates, drivers must slow down and check for trains in both directions, on all tracks. If you see or hear a train – no matter how distant it may seem – you must come to a full stop before the crossing until it has passed. Then, proceed with caution. Trains move at great speed and cannot stop quickly.

Drawbridge Signals and Signs

Drawbridges are sometimes built across bodies of water which are frequented by marine traffic, such as fishing vessels and recreational boats. Signs, signals and other warning features are installed on drawbridges, to help keep pedestrians and motorists safe.

Pavement Markings

Like signs and signals, pavement markings communicate vital information to road users about what they must or must not do on a stretch of road. Every line, symbol, letter and block color painted on a road is there for a reason, though it may not be immediately obvious to the untrained eye.

Standard Road Line Markings

Standard Road Markings

Most pavement markings you will encounter are painted lines, or patterns formed with painted lines. A great deal of information is held in these simple markings. Painted pavement lines are used to regulate traffic flow, define lanes, reinforce road signs or cordon off parts of the roadway which drivers must avoid.

Work Zone & Highway Construction Signs

Most road signs used around highway construction and maintenance sites are orange, with black text or symbols. You will encounter these signs if work being conducted on or close to the roadway presents a hazard and demands that drivers proceed with caution and reduce their speed.

Recognizing Road Signs by Shape and Color

Based on its color and shape, the general meaning of a road sign can be determined without too much thought. Road signs were purposefully designed this way, as high-speed roads and distracting environments do not afford drivers much time to consider the meaning of a single sign.

Traffic Signals

Like road signs, traffic signals are designed to communicate important information about current or upcoming road conditions to motorists and pedestrians. They are also used to control the flow of traffic, telling drivers when they must stop, prepare to stop or proceed.

Traffic Signals for Drivers

At controlled intersections, traffic lights are installed to keep multiple lanes of traffic flowing and prevent crashes. These signal lights are programmed to avoid conflicts between road users while allowing traffic to move through the intersection as freely as possible. This article will teach you how to interpret traffic lights.

Pedestrian Traffic Lights

Many intersections have signals to manage pedestrian traffic. Intersections are high-risk areas for all road users, though they pose a significant danger to people seeking to cross the street. Pedestrian signal lights at an intersection crosswalk MUST be obeyed, as motorists will not be prepared for people to step out into the road under a “DON’T WALK” sign.

Reversible Lane Control Signals

Some multi-lane roadways feature reversible lanes, where the direction of traffic can be changed to accommodate heavy traffic moving in one direction at certain times and the opposite direction at others. Traffic lights visible in both directions are installed above reversible lanes, to let drivers know whether they may use it.
