Excerpts from the UK Highway Code:
From #91 Driving when tired
"the most effective ways to counter sleepiness are to drink, for example, two cups of caffeinated coffee and to take a short nap (at least 15 minutes)"
From #206 Drive slowly and carefully when
"passing parked vehicles, especially ice cream vans; children are more interested in ice cream than traffic and may run into the road unexpectedly".
From #224 Electric vehicles
"Be careful of electric vehicles such as milk floats and trams."
From #228 Driving in icy and adverse weather
"Take an emergency kit of de-icer and ice scraper, torch, warm clothing and boots, first aid kit, jump leads and a shovel, together with a warm drink* and emergency food in case you get stuck or your vehicle breaks down."
* Evidence that these guidelines are only intended for trips of limited duration....
