Polish drivers warned about low‑rev damage, bike‑right‑of‑way, sign rules and fuel‑reserve risks

Mechanics caution that keeping engine speed below 1,300‑1,500 rpm can lead to severe wear, including valve deposits, overheating, crankshaft fractures and damage to oil pumps, injectors and dual‑mass flywheels, with repairs costing thousands of zł.

Polish traffic law requires vehicles approaching a designated bike crossing to yield to cyclists already on the crossing, and turning vehicles must give way to cyclists proceeding straight. The D‑6 series signs impose a duty to reduce speed near pedestrians and cyclists, and violations can shift liability to drivers.

Certain road signs do not automatically end speed limits, overtaking bans or stopping prohibitions at every intersection; exceptions apply on dual carriageways, residential zones and specially organized traffic areas. Misinterpretation can result in fines and penalty points.

Driving on the fuel reserve strains the fuel pump and injectors, can cause overheating, engine stall and air‑locked systems. If the vehicle stops due to lack of fuel, drivers may face a fine of 100‑300 zł and one penalty point.

France has introduced a blue sign with a white rhomb to mark car‑pool lanes. Using these lanes without the required passenger or qualifying vehicle can incur a €135 (≈ 600 zł) fine, enforced by traffic cameras.
