4D SafeHalo


SafeHalo disables mobile phone functions that distract drivers (visually, physically and cognitively) while allowing functions such as hands-free technology and emergency phone calls to remain intact. It provides a seamless user experience that works in any vehicle, with any phone. If someone enters the passenger seat position, the anti-distraction controllers will automatically change the configuration of the 4D SafeHalo to allow the passenger to use their phone, unimpeded.

Type of Technology:

Phone application, in-vehicle system (hardware software combination)

Target Audience:

Young drivers and commercial drivers

Manufacturer and Country of Origin:

4D Driving Technologies (Canada)


Currently in the pilot phase, it is proposed that SafeHalo will be made available online or in conjunction with insurance companies and telematics companies in the fall of 2019.

Means of Activation:

The 4D SafeHalo telemetry hub is installed in the OBD II port of the vehicle and another beacon is installed out of sight within the vehicle. The hardware components communicate with the operating system of the mobile device to locate the driver’s phone. Once the driver’s mobile phone is located and the vehicle is put into gear, SafeHalo disables certain functions on the phone (e.g. text, social media, data).


SafeHalo ensures that access to the driver’s device is restricted. However, passengers can operate their devices freely, unless their device enters the driver’s space.


Once the software has been downloaded in the phone, the driver is unable to opt-out of the 4D SafeHalo. Some phone functions are rendered inactive once they are in the area covered by SafeHalo. If the driver tries to disable the telemetry hub, the phone is disabled and the authority (parent or fleet manager) is notified.
