Carjacking is on the rise and authorities are on their toes in trying to prevent them. They have ready advice on how to do this.

These are just a few. Certainly, there are more. An effective way of warding off carjacking is by installing an anti-carjack alarm. There are several kinds. One kind has a shut-off system that disables itself when a thief takes possession of the car. Another is a tracking device that can monitor the car through a GPS.

• Always travel with the doors locked.
• Remain in your car if it is hit from behind by another vehicle. Inspect any damage only once you are sure it is not a hijack attempt.
• Be aware of anybody who approaches your car or is loitering near traffic lights, stop streets, parking areas or your driveway.
• Constantly monitor what vehicles are travelling behind you, ahead of, and next to you. More than one vehicle could be involved and they could be setting a trap to stop you. If you are suspicious of vehicles around you, take responsible action to get out of the situation.
