🚧 How Much Authority Does a Traffic Control Person Have?
In construction zones, it’s common to see motorists eager to move quickly—but it’s important to recognize that Traffic Control Persons (TCPs) play a critical legal and safety role.
📜 Under the Motor Vehicle Act (Part 3, Sections 122, 138, 139, 141, 141.1 and 142), TCPs have the authority to direct traffic, and all motorists and pedestrians are legally required to follow their instructions. Their authority is essential to maintaining safe and efficient movement through work zones.
TCPs often work 10–12 hour shifts in challenging weather conditions, remaining vigilant to identify and respond to potential hazards. Their responsibility extends beyond traffic flow—they are safeguarding workers, the public, and the overall job site.
WorkSafeBC’s Occupational Health and Safety Regulation (Section 18.6(2)) outlines situations where TCPs are mandatory, including:
• When traffic cannot safely self-regulate
• When single-lane traffic requires manual control
• When existing signals or systems are insufficient
• When work impacts intersections
• When traffic speed or volume poses risks
• During emergency situations without adequate traffic devices
Safety is their top priority—and public compliance is critical.
Respecting TCPs isn’t just about following rules—it’s about protecting lives.
