#1167 UK Drivers

In the UK, it is recommended that drivers should turn off their car engines when they expect to be stationary for more than 1 minute. To encourage drivers [1] off their engines while waiting at rail crossings, the Kent city council placed a permanent sign at the crossing asking drivers to "please switch off your engine when barriers are down to help improve air quality."
