Speed limits in Croatia are regulated by the Road Traffic Safety Act (Croatian: Zakon o sigurnosti prometa na cestama).
Four general speed limits apply on Croatian roads:
Lower speed limits apply to buses, heavy, trailer and towing vehicles, and tractors.[3]
The limits shown above apply only if there are no other signs present, as the signs may prescribe a lower or a higher speed limit or enforce a traffic rule that affects speed.[4]
Due to legal requirements for speed measuring, there is a tolerance of 10 km/h under 100 km/h, and 10% above that.[5]
Limits of 100 km/h or higher can also be found within inhabited places. The lowest legal speed limit under normal traffic conditions is 40km/h.[6]
Depending on the severity of the violation, driving faster than the speed limit is punishable by a fine in the amount between HRK 300 and 20,000 (roughly €40–2650). Exceeding the speed limit by more than 50 km/h in a populated area may also be punished by imprisonment of up to 60 days.[7] [5]
