The Ghana Police Service (MTTD) has deployed automated radar speed cameras across major Greater Accra transit links:

🛡️ Road Safety Tips:

• Approaching Alert: SpeedCheck warns you before reaching the limit to allow smooth braking.
• Urban Centers: The default speed limit in Accra town areas is 50 km/h unless otherwise posted.
• School & Hospital Feeder Roads: Strictly 30 km/h.

Got It

Your car dashboard almost never displays your true ground speed. Here is what motorists in Ghana need to know:

🛞 1. Tyre Sizes (Abossey Okai Swaps)

Speedometers measure wheel revolutions. Swapping rims or tyres with different overall diameters changes how far you travel per turn. Larger tyres mean you are moving faster than your speedometer says!

🇺🇸 2. American Imports (MPH vs KM/H)

Many US salvage and direct imports show MPH on the large dial:

• 31 MPH = 50 KM/H (Urban limit)
• 50 MPH = 80 KM/H (Highway limit)
• 60 MPH = 97 KM/H (Over limit!)
• 80 MPH = 129 KM/H (Dangerous violation)

🛰️ 3. GPS Satellite Ground Truth

Police radars and automated Traffitech cameras calculate true velocity across the earth. SpeedCheck uses satellite Doppler shift to deliver true ground speed, matching what enforcement cameras actually detect.

Understood

SpeedCheck is ad-free and does not upload GPS location data.

1. Location Data

Your GPS coordinates are processed in your browser and are not uploaded to SpeedCheck servers. Warning and violation history, including GPS coordinates, is stored in this browser's local storage (up to 100 records) until you clear it. CSV export is user-initiated.

2. Zero Tracking & No Ads

SpeedCheck does not use cookies, advertising identifiers, or analytics trackers. Everything runs client-side on your device.

3. Offline & Standalone

All core detection and voice algorithms function entirely offline once cached.

Close

SpeedCheck requires GPS Location access to measure your driving speed in real-time and alert you before you reach MTTD speed camera traps.

🔒 100% Private: Your GPS coordinates stay strictly on your phone and are never sent to any server.
