Is the predication correct in this sentence, it seems right to me.

Question

The driving exam is when one is tested on the rules of the road.

Thank you for using the Jiskha Homework Help Forum. Grammatically it is o.k.

The adverb clause when one is tested on the rules of the road can't be used following the linking verb is. A correct sentence would be The driving exam tests people on the rules of the road.

I wasn't completely correct in saying that an adverb clause can't be used after a linking verb. There are occasions when it is permitted. However, it isn't correct to use an adverb clause in this sentence. For more information and explanation, please check out this site.
