New Mexico General Knowledge Test

About the New Mexico General Knowledge Test

New Mexico's roads aren't flat. You'll navigate steep mountain passes like Raton Pass and long stretches of desert highway on I-10 and I-25. Our practice test covers the skills you need for these conditions, from engine braking on downgrades to managing your air pressure in high heat.

You might haul crude oil from the Permian Basin or agricultural goods from the Hatch Valley. Either way, you'll face strong crosswinds on the open plains and sudden weather changes in the mountains. Our questions reflect real driving situations you'll encounter across the Land of Enchantment.

You don't want to fail the General Knowledge test and waste your fee. Each question comes directly from the New Mexico CDL manual. We've organized them by topic so you can focus on your weakest areas first. Take the test until you score 80% or higher – that's what you'll need at the MVD.

What This Test Covers

• Air brakes – essential for controlling heavy loads on steep mountain grades in the Sangre de Cristo range.
• Combination vehicles – you'll often pull doubles or triples on I-10 and I-40 through high winds.
• Transporting cargo – secure loads properly for the strong gusts common on New Mexico's open plains.
• Driving logs – New Mexico DOT checks hours frequently near ports of entry like Las Cruces.
• Road signs – learn to spot warning signs for curves and steep hills on US-64 and NM-68.
• Vehicle inspection – crucial for desert heat and dust that damages tires and batteries.

Study Tips

Study the New Mexico CDL manual – it's available at any MVD office or online. Pay special attention to the sections on mountain driving and brake adjustments. Take our practice test multiple times – you'll see questions that mirror the real exam.

Visit the MVD website to schedule your test – appointments are required. Bring your permit, medical card, and proof of identity. Arrive early; some locations like the Albuquerque MVD get busy.
