Speed Cameras in Montgomery County

Speed cameras Montgomery County drivers should know

Montgomery County speed cameras are run through the Montgomery County Police Department automated traffic enforcement program. State law allows local speed monitoring systems in Montgomery County on residential district highways with a maximum posted limit of 35 mph, in school zones with posted limits of at least 20 mph, and on certain high-risk highways identified in approved safety plans, with limits on controlled-access highways, expressways and interstates.

A Montgomery County speed camera ticket is triggered only when the recorded speed is at least 12 mph over the posted limit. The county’s official Montgomery County speed camera locations list includes named corridors and individual block locations, and the listed blocks may include both directions of travel. Drivers should treat the posted sign as the rule, not the presence or absence of a visible camera box.

School-zone speed cameras may operate Monday through Friday from 6:00 a.m. to 8:00 p.m. State law sets that window for school-zone systems. For non-school residential or high-risk locations, check the posted signs and the citation information, because the school-zone time limit is not the same as a countywide camera-hours rule.

• Fixed and portable speed cameras
• Mobile van enforcement
• School-zone and residential-road enforcement
• No confirmed county point-to-point average-speed program

Red light cameras in Montgomery County

Red light cameras Montgomery County drivers encounter are a separate program from speed cameras. They monitor signalized intersections for vehicles entering after the signal has turned red. The county says police review and approve citations before they are issued, and the violation notice is sent to the registered owner.

A red light camera citation is a civil matter similar to a parking ticket. The county also states that right turns on red are enforced when the driver fails to come to a complete stop before turning. The county does not publish a simple countywide daily operating window for red light cameras, so drivers should assume monitored intersections can be active whenever the signal is operating.

• Signalized intersections
• Right turn on red stop violations
• Registered owner receives the notice

Tickets, delivery and contests

For speed camera citations, Maryland law requires the mailed notice to include the vehicle registration, the charge, location, date and time, recorded image, fine amount and instructions for contesting liability in District Court. For Maryland-registered vehicles, the citation generally must be mailed no later than 2 weeks after the alleged violation; for out-of-state vehicles, the period is 30 days.

A recipient may pay the civil penalty or elect a District Court trial. Paying is treated as resolving the citation, while failing to pay or contest on time can lead to registration consequences. If the owner was not driving, state law describes a sworn statement process and supporting evidence for court consideration. This guide is educational only, so follow the exact instructions printed on the citation.

Speed camera civil penalties in Maryland are tiered: $40 for 12-15 mph over, $70 for 16-19, $120 for 20-29, $230 for 30-39 and $425 for 40 mph or more over. A camera citation is not a moving violation, does not add license points and may not be used for insurance rating. If you use the Speed Camera Radar Detector app, set alerts before driving and still rely on posted signs and safe speed choices.

Work zones and local speed limits

Work-zone automated speed enforcement in Maryland is handled through the statewide SafeZones program, not as a Montgomery County neighborhood-camera program. SafeZones can be used in eligible work zones where the pre-work-zone posted speed limit is 45 mph or greater. The state program uses enforcement vehicles that rotate among work zones, and work-zone fines use a separate tiered schedule that can double when workers are present.

Local posted speeds vary widely across Montgomery County. Many neighborhood, business district and downtown streets are posted around 25-35 mph, school zones may be lower or time-based, and larger state routes can be higher. Maryland’s general speed-limit guidance lists 30 mph for business districts and undivided highways in residential districts unless otherwise posted, so the sign on the road is the controlling number for a driver.

The safest approach is to read every posted speed sign, slow before school and work zones, and expect enforcement to be concentrated where people walk, bike, board buses or cross multi-lane roads.

• School areas and walksheds
• Residential streets at or below 35 mph
• Crash-risk corridors
• State highway work zones
