How Proper Maintenance Can Prevent Them
Trailers are essential tools for transporting goods, equipment and even recreational vehicles. However, when not properly maintained, trailers can become a significant safety risk on the road. Trailer accidents are unfortunately common and often result in severe consequences, not just for the driver, but for other road users as well. Proper trailer maintenance plays a crucial role in preventing these accidents, ensuring both the safety and longevity of your trailer.
In this article, we will look at the most common trailer accidents and how a well-maintained trailer can help avoid these potentially dangerous situations.
- Jackknife Accidents occurs when the trailer swings sideways at a sharp angle to the towing vehicle, creating a “V” shape. This often happens when a trailer’s wheels lock up while braking, causing the trailer to slide and whip around the tow vehicle. The consequences of a jackknife can be catastrophic, especially on high-speed roads or in traffic.
How Proper Maintenance Prevents It: Jackknife accidents are often caused by issues with the trailer’s braking system or uneven weight distribution. Regular maintenance of the braking system, including ensuring that the brakes are properly adjusted, the brake pads are in good condition and the brake lines are free of leaks, can prevent these situations. Additionally, maintaining the trailer’s suspension system and ensuring even load distribution will keep the trailer stable while towing.
- Trailer Swaying or Oscillation occurs when the trailer begins to swing from side to side behind the tow vehicle, often caused by factors such as wind, uneven load distribution or driving at high speeds. Excessive sway can be a serious hazard, leading to loss of control and potentially causing accidents with other vehicles.
How Proper Maintenance Prevents It: One of the key causes of trailer sway is poor suspension or alignment, as well as improper load distribution. Keeping your trailer’s suspension system in top condition and checking for any signs of misalignment will reduce the likelihood of swaying. Additionally, regularly inspecting and balancing the tyres will ensure that the trailer is stable when towing, particularly at higher speeds or in windy conditions. Properly securing the load so that it is evenly distributed can also reduce the risk of sway.
- Tyre Blowouts: are one of the most common causes of trailer accidents. A blowout occurs when a tyre bursts, often leading to loss of control of the trailer. Blowouts can be caused by under-inflation, overloading or simply driving on tyres that are worn out or damaged.
How Proper Maintenance Prevents It: Regularly checking the tyre pressure and ensuring it meets the manufacturer’s specifications can significantly reduce the risk of a blowout. Worn-out tyres should be replaced immediately and it’s essential to inspect the tyres for any visible damage, such as cracks or bulges. During routine maintenance, don’t forget to check the wheel bearings, as faulty or worn-out bearings can lead to overheating, which also contributes to tyre blowouts.
- Loss of Trailer Coupling: occurs when the hitch between the trailer and tow vehicle fails, causing the trailer to detach while on the road. This type of accident is extremely dangerous, as the unhitched trailer can careen across lanes, causing accidents with other vehicles or even rolling over.
How Proper Maintenance Prevents It: Routine checks of the trailer’s hitch and coupling mechanism are essential. Ensure that the coupler is properly aligned, the locking mechanism is secure and that there are no signs of wear or corrosion. Checking the safety chains for proper attachment and condition is also vital to ensure that even if the hitch were to fail, the chains would prevent the trailer from fully detaching. Regular inspections will help you spot early signs of wear before they lead to serious issues.
- Overloaded Trailer Accidents: Overloading is a common cause of trailer accidents, as it puts excessive strain on the trailer’s frame, suspension and tyres, often resulting in structural failure or loss of control. An overloaded trailer is more prone to swaying, tyre blowouts and even brake failure, increasing the risk of accidents.
How Proper Maintenance Prevents It: Knowing your trailer’s weight limits and regularly inspecting the frame, axles and suspension components for signs of wear or damage is critical. A professional inspection can identify any weaknesses caused by overloading or excessive wear over time. Maintaining proper weight distribution is also key to preventing overloading, as it ensures that the trailer’s load is balanced and not putting undue stress on any one area. Ensuring that the trailer’s axles and suspension are properly aligned and in good condition will help reduce the likelihood of overloading-related accidents.
- Loss of Control Due to Worn Brakes: Trailer braking problems are another leading cause of accidents, especially when it comes to braking at high speeds or during emergency stops. Worn-out or improperly adjusted brakes can cause the trailer to take longer to stop, increasing the risk of collision or loss of control.
How Proper Maintenance Prevents It: Regular brake maintenance is essential to ensuring that your trailer can stop quickly and effectively. Check the brake pads and shoes for wear, inspect the brake lines for leaks and ensure that the brake controller is working properly, especially for electric brake systems. Adjusting the brakes and ensuring they are synchronised with the tow vehicle’s braking system will prevent uneven braking, which can cause the trailer to fishtail or sway during a stop.
- Inadequate Lighting and Visibility: Accidents often occur due to poor visibility, especially when a trailer’s lights aren’t functioning properly. Without working brake lights, turn signals or reflectors, other drivers might not be able to anticipate your trailer’s movements, leading to collisions.
How Proper Maintenance Prevents It: Regularly check that all trailer lights—including brake lights, tail lights, turn signals and hazard lights—are in good working order. Inspect the wiring for signs of wear, corrosion or loose connections. Ensuring that the electrical system is properly maintained and that all lights are visible will reduce the chances of accidents occurring due to poor visibility. Also, check that the reflectors on the trailer are clean and in good condition.
- Structural Failures: Structural failures, such as cracked frames or weakened chassis, can result in catastrophic accidents if left unchecked. These types of failures often occur as a result of overloading, poor maintenance or damage to the frame over time.
How Proper Maintenance Prevents It: Regularly inspect the chassis and frame for any signs of cracks, rust or structural damage. The frame bears the brunt of the weight, so keeping it in good condition is essential for safe towing. If any damage is detected, it’s crucial to address it immediately to avoid potential structural failure while on the road. Preventative maintenance, including keeping the trailer clean and addressing rust before it spreads, can help preserve the structural integrity of the trailer.
- Poor Road Handling Due to Misalignment: Misalignment of the trailer’s wheels or suspension can lead to handling problems, including swaying, uneven tyre wear or difficulty in keeping the trailer straight on the road. Poor handling increases the risk of an accident, especially when navigating turns or driving at high speeds.
How Proper Maintenance Prevents It: Alignment checks should be performed regularly, particularly after any incident that could have affected the trailer’s suspension or frame, such as hitting a pothole or curb. Ensuring that the wheels are aligned properly and the suspension system is in good condition will allow the trailer to handle smoothly and reduce the risk of accidents.
