How it fits
Electronic transponders and licence-plate imaging can support free-flow collection.
Operations
Tolls can fund infrastructure or help manage demand, depending on the project.
Canadian context
Payment methods, exemptions and enforcement are facility-specific.
Limits and lifecycle
Users should check the governing facility rather than assume one national tolling system.
General infrastructure education only. Active road incidents, vehicle recovery and technical road work should follow responsible authorities and qualified professionals.
