ABSTRACT:
An alarm for waking a dozing driver includes a plurality of electrical switches arranged about the steering wheel of a vehicle. A rigid member extends continuously about the steering wheel and is resiliently attached thereto and arranged with respect to the switches so that a normal grasp of the steering wheel causes the rigid member to be displaced and at least one of the plurality of switches to change from its normal position. Alarm means are electrically connected with the plurality of switches and with a power supply so that the change of state of a switch from its normal position deactivates the alarm means.
