Take another look at the sentence:
Dan would have __________ his new truck to the grocery store if he hadn't been so worried that a loose can of peas might roll around in the bed and chip the pristine green paint.
The sentence requires the past participle of drive, an irregular verb. Driven is the past participle.
|Verb||Simple Present||Simple Past||Past Participle|
Drived, the form you chose, is a spelling error. Before you continue, review the rules for irregular verbs.
