How do you know if your trailer is equipped with antilock brakes?

To determine if your trailer is equipped with antilock brakes (ABS), check for a warning light on the trailer's brake controller, which indicates the presence of ABS. You can also look for an ABS module or a small electronic control unit near the trailer's axle. Additionally, consult the owner’s manual or the manufacturer’s specifications for your trailer model, as they typically provide information on the braking system. If in doubt, you can contact the manufacturer or a qualified mechanic for verification.
