We're being reminded not to drive home under the influence, if we're out at Christmas parties this weekend.

Avon and Somerset Police will be making stop checks of vehicles and targeting known hotspots at peak times as part of Operation Tonic - which has now seen 99 arrests since December the first.

Thery're also asking us to text the work 'drunk' to 81819 if we see someone getting behind the wheel who's drunk or on drugs.
