This warning sign indicates a crossing with a tramway that lacks barriers. Trams can approach quickly and are often quiet until close, and they cannot swerve, so you must yield and avoid entering their path. Reduce speed and scan for trams from both directions, especially if buildings or parked vehicles restrict visibility. Also be aware that rails can be slippery when wet or icy, and can affect braking and steering, particularly for cyclists and motorcyclists. Cross rails at a safe angle and avoid sudden braking on the tracks.
This sign warns of unevenness or damage in the roadway that makes it suitable to travel at a lower speed than you otherwise would. The hazard can include potholes, ridges, settlements, or patched surfaces that affect vehicle stability. Uneven surfaces can lengthen stopping distance, reduce steering precision, and increase the risk of losing control, especially for motorcyclists and cyclists. Reduce speed, hold the steering wheel firmly, and keep extra distance to avoid sudden braking if the vehicle ahead swerves. At night, uneven surfaces can be harder to spot, so keep good attention and appropriate lighting.
