Final answer:
When driving on the road with cyclists, drivers need to be aware that cyclists are permitted to ride in the middle of the lane and they can move over suddenly.
Step-by-step explanation:
When driving on the road with cyclists, drivers need to be aware of several things. Firstly, cyclists are permitted to ride in the middle of the lane, especially when there is not enough space for a vehicle to safely pass. This is important for drivers to understand so that they do not try to pass too closely and risk colliding with the cyclist.
Secondly, drivers need to be aware that cyclists can sometimes move over suddenly, either to avoid obstacles or to make a turn. It is important for drivers to give cyclists enough space and be prepared to react accordingly in these situations.
Therefore, the correct answer is C, all of the above.
