Free California CDL Permit Practice Test: General Knowledge 2024 | CA

Hello, future California trucker! Ready to hit the Golden State’s highways? Well, this free California CDL General Knowledge practice test is your first stop.

We’ve lined up 50 questions, all based on the 2024 California CDL handbook -- it’s as fresh as the produce you might be hauling through the Central Valley.

Driving in California is not quite like anywhere else. One minute you’re chugging up the Grapevine; the next you’re inching your way through LA traffic. We’ll test you on the following:

-- Up and over steep grades in the Sierra Nevada

-- Dealing with Santa Ana winds blowing in SoCal

-- Managing your rig in dense fog in the Central Valley

-- Special rules for ports in Long Beach and Oakland

But it’s not just about driving skills; you’ll also want to know California’s unique regs. Like, what’s the deal with the CARB emissions standards? Or the rules of transporting almonds during harvest season?

Each question has an explanation that accompanies it. Do not skip these -- they are full of California-specific knowledge that may save you a headache down the road.

Remember, in California, we don’t just train drivers; we build pros who can take everything from desert heat to coastal fog. This test is your first gear toward joining these elite drivers who keep the economy of California chugging along.

So go ahead, blend up that avocado smoothie, pop on some Beach Boys, and we’re gonna see if you’ve got the stones for that California CDL. Good luck!
