Speed limits and fines for rental tuk tuks.

The absolute maximum legal speed limit for a three wheeler tuk tuk anywhere in Sri Lanka is strictly 40 kilometers per hour. Traffic police frequently set up radar traps along the long, straight coastal highways specifically targeting speeding vehicles. If you exceed 40 km/h, you will be pulled over and hit with an instant, hefty spot fine. Driving slowly is not just legally required, it is highly crucial for your safety, as tuk tuks have notoriously poor braking systems and can easily flip if cornering at high speeds.
