General Motors has begun equipping its 2017 Cadillac CTS sedans with upgraded communications capabilities.

The technology, known as vehicle-to-vehicle or V2V, allows automobiles to share information about road conditions, closures, and hazards.V2V-equipped cars send and receive information on their speed and location with each other.

General Motors says V2V will be standard equipment on 2017 CTS sedans pending a mid-year update.

V2V allows the Cadillac CTS sedans to receive 1,000 messages per second from vehicles that are nearly 1,000 feet away, the company says.

"Connecting vehicles through V2V holds tremendous potential, as this technology enables the car to acquire and analyze information outside the bounds of the driver's field of vision," said Richard Brekus, Cadillac's global director of product strategy. "As an early mover, we look forward to seeing its benefit multiply as more V2V-equipped vehicles hit the road."

Cadillac's implementation of V2V technology allows the CTS to display warnings of disabled vehicles, slippery roads, and other hazardous situations – right on the dashboard.Drivers can specify whether they would prefer to see V2V data on the dashboard with the rest of the car's instrument displays or on a heads-up display projected on the interior of the windshield.

The U.S.Department of Transportation has proposed that all new cars include inter-vehicle communication technology starting in 2023.
