What should you do? You must exit a highway using an off-ramp that curves downhill.
A. Come to a full stop at the top of the ramp. B. Wait until you are in the curve before downshifting C. Slow down to a safe speed before the curve. D. Slow down to the posted speed limit for the off-ramp
Get in slow lane before your intended exit ramp comes up, drive with the flow of traffic. Guidance on exit ramp advisory speeds is limited and based primarily upon horizontal curvature. Guidance is provided with a certain amount of flexibility.
You should slow down to a safe speed before the curve. Merging into fast flowing traffic on a motorway requires practice and precaution. Downhill ramps give much better visibility across the whole motorway whereas uphill ramps cause a blind spot over the crest of the rise.
Downhill slopes are preferable as they provide vehicles a much better chance to get up to the same speed of traffic on the motorway. Never go too fast around a curve.
