Practice for the Canadian commercial driver knowledge test
Canada Commercial Licence Prep is an offline iOS study app for the provincial and territorial commercial driver knowledge tests. Pick your province and your licence class, and the whole app — the question bank, the mock test length, the pass mark and the topic weighting — filters to the test you are actually sitting.
