Listening to something while driving is as dangerous as drunk driving, a research said. 

An American team research concluded that even the simple ask  of listening to someone speak while driving at the same time  " reliably degraded driving performance" .

A car radio or a gossipy passenger can impair driving in a manner similar to drunk driving , so that the driver is more likely to weave in and out of the borders of a lae on a motorway .

The participants listened to general knowledge questions and verified them as true and false using buttons in their other hand and performance on the simulated driving test was assessed. The study shows that the addition of listening task decreased the brain activity associated with performing a driving task by 37 per cent .

The researchers observed that driving while listening resulted in much poorer quality of driving.
