What Are Trailer Chocks and How Do You Use Them on Trailers?

Writer's picture: BrentBrent

One of the most underrated bits of kit in the trailer world are - trailer chocks. Now, these little blocks might not seem like much, but trust me, they can make all the difference when it comes to trailer safety. Whether you’re parking your trailer on a slope or just want to keep it secure while loading, chocks are a must. Let’s dive into what they are, why you need them, and how to use them like a pro.


What Are Trailer Chocks?

Trailer chocks are wedge-shaped blocks, usually made from rubber, plastic, or metal, designed to prevent your trailer from rolling when it’s parked. They work by sitting snugly against the tyres, acting as a barrier that keeps the wheels in place. It’s a simple concept, but chocks can save you from some serious trouble—especially when you’re parked on uneven ground or a hill.

The basic idea is to stop your trailer from moving when it’s unhitched from your vehicle. Even if you’ve applied the handbrake, it’s always a good idea to throw some chocks behind the wheels for added security.



Why You Need Trailer Chocks

So, why bother with chocks? Here’s why they’re essential:


1. Safety First

The most important reason for using trailer chocks is safety. Trailers can and do roll when you least expect it, and you don’t want to be chasing after yours as it careens down a hill. Chocking your wheels helps prevent accidents, which is especially important if you’re parked on a slope or loading and unloading heavy gear.


2. Stability When Unhitching

When you unhitch your trailer from your vehicle, there’s a moment where the trailer might start to shift. Chocks give you that extra bit of peace of mind, keeping the wheels locked in place while you’re getting everything set up.


3. Prevent Damage

Let’s be honest—having your trailer roll into something (or someone) isn’t going to end well. Using chocks can help prevent damage to your trailer, your tow vehicle, or anything else in the vicinity.


When and Where to Use Trailer Chocks

Wondering when you should be using trailer chocks? Here are a few situations where they’re a must:


1. On Slopes or Hills

If you’re parking on a hill, chocking the wheels is essential. Even a slight incline can cause your trailer to start rolling if the handbrake fails or isn’t strong enough. It doesn’t matter if it’s a paved road or a grassy hill—always use chocks to be safe.


2. When Loading or Unloading

Whenever you’re loading or unloading your trailer, especially with heavy equipment, the weight shift can cause the trailer to move. Chocking the wheels prevents any unwanted movement and keeps things steady while you work.


3. When Parked for Long Periods

If your trailer is going to be sitting parked for a while, even on flat ground, it’s a good idea to chock the wheels. Over time, the brakes can release or loosen slightly, and the last thing you want is for your trailer to start rolling after a few days of sitting idle.


How to Use Trailer Chocks

Using chocks is pretty straightforward, but here’s how to do it properly:


Step 1: Choose the Right Chocks

Make sure you’re using chocks that are appropriate for your trailer’s size and weight. Bigger trailers need more heavy-duty chocks, while smaller trailers can get by with lighter, less bulky options. Rubber chocks are a solid choice for most trailers because they provide good grip on different surfaces, but there are also metal and plastic versions.


Step 2: Position the Chocks

When you’re ready to chock the wheels, place the chocks on both sides of at least one wheel. Ideally, you’ll want to chock both wheels on both sides of the trailer, especially if you’re on a slope. Position them tight against the tyre to make sure they won’t budge.


Step 3: Chock Both Sides

For maximum safety, chock both the front and back of each tyre. This stops the trailer from rolling in either direction. If you’re parked on a slope, chock the downhill side first. It’s also important to use the handbrake in conjunction with chocks—don’t rely on one or the other alone!


Step 4: Remove the Chocks Last

When you’re ready to hit the road again, make sure to remove the chocks only after you’ve reconnected the trailer to your tow vehicle. This ensures the trailer stays in place until it’s properly hitched up.


A Few Bonus Tips

  • Store Your Chocks Properly: Keep your chocks handy and stored in an easy-to-access spot on your trailer or vehicle. You don’t want to be scrambling to find them when you need them most.

  • Use on Different Surfaces: Chocks work on a variety of surfaces—gravel, grass, asphalt—but if the ground is really loose or soft, you might want to place a plank or board underneath them to give them a better grip.

  • Double Check: Once your chocks are in place, give your trailer a gentle push to make sure everything is secure. If the trailer doesn’t budge, you’re good to go!


Lock It Down with Chocks

There you have it, mates! Chocks might be small, but they’re mighty when it comes to trailer safety. Whether you’re parked on a hill, loading gear, or just want some extra peace of mind, chocking your wheels is a simple step that can prevent a whole lot of drama.
