How this technology works
Speed alert systems help the driver stay within the speed limits. Most systems use a camera that can read speed limit information and remind drivers of the current speed limit via a display on the instrument panel. Other systems feature stored digital speed maps with GPS that display the posted speed limit and alert drivers either by a visual or audio alert when they drive above the speed limit. Newer systems combine information from both sources, a camera and digital speed map.

- Speed Alarm
A car is driving over 80 km/h on a road with an 80 km/h speed limit, prompting an alert.
Things for drivers to keep in mind
- Don't rely solely on the system for speed limit information. Stored speed limit maps may not always be accurate or up-to-date or provide coverage for all roads
- Camera systems may not always see the speed limit signs or read them correctly
- You should read your owner's manual to learn about your vehicle's system, including its capabilities and limits
