Roll over the zipper. This is the most annoying mistake made during this maneuver

The principle of rolling over the zipper it was supposed to make it easier for drivers to navigate the roads during traffic jams, renovations, and other traffic-awkward situations. Almost three years have passed since the introduction of the regulations, and many motorists still have problems interpreting the regulations.

The obligation to drive a slider is regulated by road traffic law, in particular art. 22 points 4, specifying the safety rules when changing lanes.

The exceptions described below (paragraphs 4a and 4b) require a slider stroke:

  • In the conditions a significant reduction in speed on the road, with more than one lane in the same direction of traffic, in the event that it is not possible to continue driving in the lane due to an obstacle in that lane or the disappearance of the lane, the driver of the vehicle that is moving in the adjacent lane is obliged, directly in front of the obstacle or lane disappearance pointto allow a vehicle or a combination of vehicles located on such a lane to pass onto an adjacent lane where it is already possible to continue driving.
  • In a situation of significant reduction in speed on a road with more than two lanes in the same direction of traffic, where it is not possible to continue driving in both lanes, due to obstacles in these lanes or their disappearance, if between these lanes there is a lane on which it is possible to continue driving, then the driver of the vehicle using this lane is obliged to let a vehicle or a group of vehicles change lanes on the right side directly ahead the obstacle or the disappearance of the tracks, then to a vehicle or to the group of vehicles on the left side.

For slider driving to be required, suitable road conditions must be present. There must be a significant reduction in speed due to traffic jams on the route. As a result, vehicles stop or run slower due to road obstructions (cullet, accident, breakdown, renovation or other traffic situation).

However, the above circumstances do not always require the driver to use the zipper. We do not apply this rule when the speed is simply reduced because the speed limit is lowered. The slider also does not apply when we reach the end of the inclusion or acceleration lane. Provided that there is no traffic jam for the reasons mentioned above.

When using a zipper, use the full length of the ending lane and go to the end of the lane, while maintaining vehicle speed in the adjacent lane. During this manoeuvre, absolutely remember to signal your intention with the turn signal. If we move into a lane that has a continuation, we are forced to enter the car that runs along the arrival lane.

  • Sometimes drivers block the lane to prevent others from passing at the end of the lane where it is impossible to continue driving. This behavior is often called “serifing” on the road.
  • Another common mistake is trying to push into the second lane just behind a passing car. Please note that the driver in the lane that has a continuation is required to leave only one vehicle in front of him.
  • Sometimes drivers in the lane that has continuation driving “stick” to the bumper of the car in front of them. Thus, they do not allow the vehicle to engage from the lane that ends.
  • This is perhaps the most annoying mistake made when riding a zipper: Often drivers also try to leave the lane that ends early. The zipper driving rules clearly state that you must reach the end of the lane. Only where it is impossible to continue driving, signaling the desire to change lanes and executing the maneuver.
  • Some drivers think the zipper rule applies wherever one of the lanes disappears. It’s not true. The regulations specify that there must be a significant slowdown in traffic. Only then is the cursor path valid.

The principle of the zipper considerably improves the flow of traffic in places of narrowing – provided that all drivers respect the rules. Sometimes just one “black sheep” on the road is enough to mess up the whole system.
