What is the greatest risk when you have driven onto this exit ramp?
This is a classic situation. With questions concerning exit ramps from motorways and clearways, it is almost always speed blindness that is the issue.
“When you have driven a long distance on the motorway [or clearway] and slow down at the exit ramp, you may, due to speed blindness brake, brake far too late and, for example, swerve off the road as a result.” (Driving Licence Book, 19th Edition, page 83)
The distance you have driven is admittedly not given. You must then think about how long you normally drive on a clearway. It is more than 1 minute in any case. This, in combination with the fact that the other options are not so reasonable, means that you can assume that you have driven a long distance and therefore risk speed blindness.
There is also a driving licence book online (2023).
