There are quite a number of different twitter accounts which can help you keep up to speed with what is happening on the roads around the country. Following a collection of these accounts really can make your life a whole lot more comfortable and relieve a lot of frustrations.
I have created a page listing my favourites. Since I am based in KZN most of the ones listed are from that region. Please feel free to leave more in the comments and I will add them to the list to keep it up to date regularly. For your convenience you can find a combined twitter list here : http://twitter.com/#!/jjza/traffic
