Simply, why is there a camber on the road?
Answers:
The road is convexed to allow water to runoff. Water pooling or puddling, causes vehicle Hydroplaning, a condition where a vehicle is no longer touching the road surface, and is "floating" on top of the water. Read this article for more information.

duh ! so the rain doesn't lie in the middle.
so that rain and melted snow will run off the road surface created a safer driving environment
So that rain water runs into the channels at the side of the road, there for reducing the risk of ponding and skidding/water planing.
so when it rains the water drains away. simple.
Simply, so water can drain away.
to make it ever so slightly more comlicated for learners to do 3-point turns. oh yeah and that water thing.
So the rain doesn't collect in puddles and drains away to the sides of the roads in the gutter!
Drainage.
Drains off rain, prevents hydroplaning.
To help prevent surface puddles.
So the rain runs off and dosen't flood the road surface
Drainage of water for one. This will help vehicles to avoid aqua-plaining.
There is also a camber around certain corners to aid in vehicles going around corners, certainly on motorways.
They always lay the tarmac over the water, gas and electricity pipes the bulge is there as a result.
Roads are primarily there to protect our pipes, ask any workman.
So the rain will run off.
To drain the rain.
when it is raining the water will roll down to the side away from the road surface
well its not called camber it is called a crown and it is put on the road to drain water off the roads taveled surface to the edge and in to the ditches
