The instruction to is a safety-critical regulation designed to manage high-risk traffic zones. While highway speeds typically range from 100 to 120 km/h globally, toll plazas require significant deceleration due to restricted lane widths and potential hazards. Key Safety and Operational Reasons
: Reduced limits protect toll plaza employees who may need to cross lanes and prevent collisions with concrete barriers or toll booths.
: Toll areas often have high congestion or unannounced stops. A 50 km/h limit provides sufficient reaction time for unexpected hazards. Regulatory and Enforcement Details
: While modern "Open Road Tolling" (ORT) can handle highway speeds (up to 105 km/h in some regions), older transponder systems or those integrated into traditional booths may require lower speeds to ensure the tag is read accurately.
: Lower speeds ensure drivers can safely navigate rapid speed changes and merge with traffic coming from different payment lanes (e.g., cash vs. electronic).
