Tint limits, plates and fines: rules buyers ask about

Window tint is allowed up to 30% darkness on the side and rear windows. The windshield and front-side windows must stay clear unless you obtain a medical permit through Absher. Reflective mirror films are banned, and taxis, rental cars and buses may not tint at all. Fines for illegal tint are reported in the range of SAR 500–900, and the car can be held until the film is removed.

Plates belong to the owner, not the car: when you sell, you can keep your plate and move it to another vehicle you own for a SAR 400 fee, and distinctive plates are auctioned on Absher.

Before buying any used car, check its recorded violations on Absher or Tamm — a transfer cannot complete while fines are unpaid, and sellers sometimes expect the buyer to absorb them.
