Meaning
Railroad Crossing Ahead gives advance notice that your road crosses railway tracks. Start checking for rail traffic before reaching them. The warning sign does not tell you that a train is present right now, and an apparently quiet crossing still requires your attention.
What to do
In Pennsylvania, begin looking and listening for a train on the approach. Check both directions even when warning lights are not flashing. Before driving onto the tracks, make sure there is enough room to get your whole vehicle across; a clear track does not help if traffic leaves you stuck on it.
Where it is used
The advance warning comes before the crossing, with room for a driver to prepare for a necessary stop before the tracks. Do not confuse that approach warning with the crossbuck at the tracks themselves. Use the advance distance to begin your checks, rather than waiting until the rails are under your vehicle.
A sign to tell apart
A crossbuck identifies the crossing itself. PennDOT says to treat it like Yield and prepare to stop for an approaching train. The round advance warning alerts you earlier; it does not replace the crossing’s crossbuck, signals or gates.
Practice with explanations
These are original learning questions based on the cited handbooks. Read each answer and its explanation below.
1. What should a Pennsylvania driver begin doing on seeing Railroad Crossing Ahead?
- Look and listen for a train.
- Wait until reaching the tracks to check.
- Assume no train is coming unless a gate is lowered.
Answer: A. Look and listen for a train.
The advance warning gives you time to detect a train and prepare to stop before reaching the rails.
2. Traffic beyond a Pennsylvania railroad crossing leaves no room for your whole vehicle. What should you do?
- Enter if no train is visible.
- Follow the vehicle ahead onto the tracks.
- Wait before the tracks until enough space opens beyond them.
Answer: C. Wait before the tracks until enough space opens beyond them.
Do not enter a crossing unless you can get all the way clear. Waiting traffic must not trap your vehicle on the tracks.
