I'm sure you're all aware of the Traffic Scotland website - if not you can find it at:
TRAFFIC SCOTLANDIf your'e planning a journey anywhere in Scotland take a look at this site before you leave. It'll show you any roadworks or current incidents. You can even look through the traffic cameras dotted around the area for actual weather conditions rather than rely on the likes of the Met Office to get it wrong for you.
In addition if you're planning a trip south of the border then there's an English equivalent - just found this today actually:
TRAFFIC ENGLAND I haven't had a chance to look at this site yet so don't know what features it has but it's got to be worth a look.
I've just had a look and guess what? There's even a Traffic Wales site for anyone crazy enough to want to visit the area!
