『ジーニアス英和辞典』（大修館書店）によれば，abetは「「＜犯罪を＞幇助する，＜人を＞教唆（扇動）して[・・・]を犯させる」とあります。したがって，「道路交通法違反の幇助の容疑で」と解釈できます。abetは，しばしばaid and abetの形で使われるようです。

e.g. a riot aided and abetted by the police（『ジーニアス英和辞典』同上）

　LDOCEにはto help someone do something wrong or illegalとあり，こちらの方がわかりやすく感じます。
　また，apply his brakeと「ブレーキをかける」というときには，applyを用いることも覚えておきたい表現のうちのひとつです。
