In which cases should you apply the brakes only very carefully?

You should apply the brakes very carefully in these situations to maintain control and avoid skidding. On roadways with loose chippings or sand, hard braking can cause your vehicle to skid because the surface lacks grip. On tram tracks, sewer covers, and lane markings, the surfaces are often slippery, especially when wet, so gentle braking helps prevent loss of traction. When driving for the first time with new tyres, the rubber may not have fully settled or has a different grip level, so braking gently ensures you adapt safely to the new conditions. In all these cases, careful braking helps you stay safe by reducing the risk of accidents caused by sudden loss of tire grip.
