Speed cameras are installed at fixed locations to photograph speeding vehicles in school zones. Photographs will be used to document speeding violations. If a speeding violation has been committed and is documented by a camera, the vehicle owner will receive a Notice of Liability in the mail about 30 days after the violation is committed. The owner will have 30 days from the date of the Notice to pay or dispute the violation. If you receive a Notice of Liability in the mail for a speed camera violation, the fine is $50.
