The T-13 sign warns drivers of deformed road surfaces, specifically deep ruts or grooves (koleiny) often caused by heavy trucks and heat. These ruts can be dangerous, especially in wet conditions where they increase the risk of aquaplaning, or in dry conditions where they can unexpectedly affect steering. Seeing this sign means you should reduce speed and be prepared to adjust your steering carefully to maintain control, primarily finding a safer path within your lane.
This T-13 sign warns of dangerous deep ruts in the road surface, requiring careful interpretation for safe driving. Master this road sign meaning and other traffic sign explanations to excel in your theory test revision.
The T-13 plate is used with A-11 or A-30. Ruts (koleiny) are dangerous because they can trap your tires, making steering difficult, or they can fill with water, causing severe aquaplaning. In dry weather, they can cause a car to 'jump' out of the groove unexpectedly. Drivers should try to drive slightly offset from the ruts or reduce speed significantly to maintain control over the vehicle's direction.

The T-13 sign is a warning sign that alerts you to the presence of deep ruts or grooves in the road surface, known as 'koleiny'. These are often found in lanes used by heavy vehicles and can pose a significant hazard.
Road ruts are dangerous because they can trap your tires, making steering difficult. In wet weather, they can fill with water, leading to a high risk of aquaplaning. In dry conditions, they can cause your vehicle to unexpectedly jump out of the groove, affecting your control.
Upon seeing the T-13 sign, you must reduce your speed significantly. Hold the steering wheel firmly with both hands and be prepared to make slight adjustments to avoid the deepest parts of the ruts, ensuring you maintain control of your vehicle's direction.
Road ruts are most commonly found in the right-hand lanes of national roads where there is a high volume of heavy transit traffic. These conditions are more prevalent in warmer weather when the asphalt can soften.
A common exam trap is not understanding the severity of aquaplaning risk when ruts are present and it's raining. Learners might also forget the importance of a firm grip on the steering wheel and that fighting the wheel is less effective than slowing down to regain control.
Overtaking is generally not advisable when the T-13 sign is displayed, especially if the ruts are deep or the weather is poor. Loss of traction during the maneuver in the ruts can be unpredictable and dangerous, so it's safer to wait until the road surface improves.
