The OB-503 road sign is a warning sign indicating that two-way cycle and moped traffic crosses your path. This sign is often placed beneath another warning or priority sign to highlight an intersection where smaller vehicles travel in both directions. Drivers encountering this sign must significantly reduce their speed and be vigilant, scanning to their left and right for oncoming riders before proceeding. Always ensure a safe gap before crossing, and never block the designated crossing.
The OB-503 supplementary sign specifically warns Dutch drivers about two-way cycle and moped traffic crossing the carriageway, even where general traffic flows one-way. This crucial road sign meaning ensures you reduce speed and check thoroughly for approaching riders from both sides, which is essential for your driving theory exam preparation and safe road participation.
The crossing cyclists and mopeds both directions plate is a supplementary sign placed under a warning or priority sign at junctions with a two way cycle track or moped path. It alerts drivers that riders may appear from both sides when they cross the carriageway. This is especially important where the cycle facility is set back from the road or partly hidden, so extra scanning and lower speed are needed.
This plate warns that cyclists and moped riders will cross your path from both directions at the nearby crossing. It reminds you that traffic on the cycle or moped facility is two way, even if the general traffic flows in one direction only. You must slow down in good time, check carefully to your left and right, and be prepared to yield where required.
Get clear, practical answers to the most common questions about the OB-503 - Crossing Cyclists & Mopeds from Both Directions road sign.

This FAQ strengthens your understanding and supports accurate decision making for the Dutch driving theory exam in the Netherlands.
The OB-503 sign warns you that a cycle path or moped route crosses the road you are on. Importantly, traffic on this crossing path comes from both left and right, meaning you need to check for riders approaching from either direction.
When you see the OB-503 sign, you must slow down considerably and be prepared to yield. Scan carefully in both directions for cyclists and moped riders. Only proceed when it is completely safe and there is a clear gap in traffic.
A common mistake is only checking traffic from one direction, assuming riders will only come from the left. The 'both directions' aspect is crucial. Another trap is not slowing down enough, which can lead to a dangerous situation or failing the exam for not yielding correctly.
The OB-503 itself is a warning sign; it doesn't automatically mean you must stop. However, it warns you of a situation where you will likely need to yield to crossing cyclists and moped riders. Always be prepared to give them priority, especially if it's accompanied by a yield (give way) sign.
You'll often see this sign on roads where cycle paths or moped routes intersect or run alongside. It's particularly common at mid-block crossings, shared paths, or junctions where smaller vehicles might cross your path unexpectedly from either side, often in urban or suburban areas.
