Motorbike Indicators: Legal, MOT & Safety Guide UK

For many UK motorcyclists, the question of whether indicators are legally required, particularly during an MOT, is a recurring source of uncertainty. You see plenty of bikes on the road, both old and new, and the rules can seem a bit hazy. The truth is, the regulations are specific, and understanding them is key to a smooth MOT experience and, more importantly, to your safety on the road.

The common refrain circulating among riders is often, "If a motorbike has indicators fitted, they must work, but it is not a legal requirement to have indicators on a motorbike." This statement, while containing elements of truth, needs careful unpacking to avoid misunderstandings that could lead to an MOT failure or, worse, a dangerous situation on the road.

The Core Principle: Fitted Means Functional

Let's address the primary point first: if your motorbike is equipped with direction indicators, then for the purpose of the MOT, they absolutely must work. This isn't a suggestion; it's a mandatory requirement. An MOT tester will meticulously check several aspects of your indicator system:

• Presence: All four indicator lamps (front left, front right, rear left, rear right) must be present if the bike was designed to have them.
• Operation: When activated, they must flash consistently and at the correct rate. Rapid flashing often indicates a bulb failure or a fault in the flasher relay.
• Colour: The light emitted must be amber.
• Visibility: They must be clearly visible from both the front and the rear, within specified angles.
• Lenses and Bulbs: Lenses must be intact, not cracked or missing, and all bulbs must be present and functioning. Even a single missing bulb or a broken lens on an otherwise fitted indicator system will result in a failure.
• Switch Functionality: The indicator switch on the handlebars must operate correctly, allowing you to select left, right, and cancel the signal.

So, if your Suzuki GP100 has indicators fitted but is missing bulbs and lenses, as described in common scenarios, it will undeniably fail its MOT. The presence of the units themselves, even if incomplete, signifies that they are part of the bike's signalling system, and thus must be fully operational.

When Are Indicators NOT a Legal Requirement? Understanding the Exemptions

Now, to the second part of the common statement: "It is not a legal requirement to have indicators on a motorbike." This is where the crucial nuances lie. While most modern road-going motorbikes are expected to have indicators, there are specific exemptions under UK law and MOT regulations:

• Pre-1st August 1986 Registered Machines: If your motorbike was first registered for use on the road before 1 August 1986, it is not legally required to have direction indicators. This applies even if the bike originally came with them. If you own a classic bike from this era and wish to remove the indicators, you can, and it won't be an MOT failure, provided you remove the entire system (including the switch). However, for safety, many classic bike owners choose to retain or retrofit working indicators.
• Low-Speed Machines: Motorbikes that cannot exceed a speed of 30 mph (or 50 km/h) are also exempt. This typically covers some very low-powered mopeds or scooters.
• Off-Road Machines: Bikes that are constructed or adapted primarily for use off-road (e.g., dirt bikes, trials bikes) and are designed to carry only the rider. This exemption also extends to 'off-road' machines with a sidecar designed to carry the rider and one passenger in the sidecar. The key here is their primary design and intended use.

It's important to stress that these exemptions apply to the requirement to have them. If a bike in one of these categories does have indicators fitted, then they still fall under the "fitted means functional" rule and must work to pass the MOT.

The Critical Role of the Indicator Switch

One of the most frequent causes of confusion and MOT failure, even when indicator units are removed, revolves around the indicator switch. As highlighted in the discussion, "If the switch is still there that's deffo a fail." This is a critical point that many riders overlook.

The presence of an indicator switch on your handlebars implies that the bike is designed to have indicators and that the system should be operational. If the switch is there but the lights are missing, broken, or non-functional, an MOT tester will interpret this as a faulty signalling system, leading to a failure. It's a clear indication that a safety feature is present but not working.

Therefore, if your motorbike falls into an exemption category and you decide to remove the indicators entirely, you must also remove the indicator switch. Simply covering it with tape might not be sufficient, as a thorough tester could still identify its presence. For a clean MOT pass, if no indicators are required and you don't want them, ensure both the lights and the control switch are completely absent from the bike.

Practical Advice for Motorbike Owners

Given the intricacies of the rules, what should you do if you're facing an MOT with questionable indicators?

Scenario 1: Your Bike Requires Indicators (Most Common)

If your bike was first used on or after 1 August 1986, and it's a road-going machine, it almost certainly requires working indicators if it was originally fitted with them (which most were). In this case:

• Repair is Paramount: Your best course of action is to repair any faulty indicators. This means replacing blown bulbs, fixing wiring issues, securing loose connections, and replacing any missing or damaged lenses. Ensure they flash at the correct rate and are clearly visible.
• Don't Attempt to Deceive: Do not try to remove some parts and leave others, or simply tape over faults. A competent MOT tester will spot this, and it will result in a failed test.

Scenario 2: Your Bike is Exempt (e.g., Pre-1986 Classic)

If your bike genuinely falls into one of the exemption categories (e.g., a pre-1986 Suzuki GP100 if it was indeed registered before that date, or a dedicated off-road machine):

• Complete Removal: To guarantee an MOT pass without indicators, you must remove the entire system. This includes all four indicator lights and, crucially, the indicator switch on the handlebars. If the switch remains, it's a fail.
• Consider Safety: Even if exempt, consider the safety implications of not having indicators. Hand signals are legal but are significantly less visible and effective, especially in challenging conditions. Many riders choose to fit small, discreet, but effective LED indicators even on exempt bikes for enhanced safety.

The Importance of Indicators for Road Safety

While the legalities and MOT requirements are important, it's vital not to lose sight of the primary function of indicators: safety. Direction indicators are a crucial communication tool between you and other road users. They inform drivers behind you, in front of you, and beside you of your intention to turn, change lanes, or pull over. Without them, you rely solely on hand signals, which can be:

• Less Visible: Especially at speed, in busy traffic, or in low light conditions.
• Ambiguous: Some hand signals can be misinterpreted.
• Compromised Control: Taking a hand off the handlebar to signal reduces your control over the bike, which can be particularly risky in challenging situations.

In the unfortunate event of an accident, if you were not signalling your intentions clearly, it could also have implications for insurance claims, even if your bike was legally exempt from having indicators. The principle of exercising due care and attention on the road extends to making your intentions clear to others.

Table: Indicator Scenarios and MOT Outcomes Summary

To provide a clear overview, here's a summary of common scenarios and their likely MOT outcomes:

Frequently Asked Questions (FAQs)

Q1: Can I just use hand signals instead of indicators?

A1: Yes, hand signals are legally permissible for indicating your intentions on a motorbike in the UK. However, as discussed, they are significantly less visible and effective than modern indicators, especially in challenging conditions. For safety, indicators are always recommended.

Q2: My bike is old, but it still has indicators. Do they have to work for the MOT?

A2: Yes. If your bike has indicators fitted, regardless of its age, they must be in full working order to pass the MOT. The exemption for pre-1986 bikes only applies if the indicators are *not* fitted at all.

Q3: What if only one indicator is not working?

A3: Even if only one indicator is faulty, it will result in an MOT failure. All fitted indicators must be operational.

Q4: My aftermarket indicators are very small. Are there minimum size requirements?

A4: Yes, there are regulations regarding the size, position, and visibility of indicators. While small LED indicators are popular, they must still meet the required surface area and light output standards to be legal and pass an MOT. Always check that aftermarket parts are 'E-marked' or 'CE-marked' where appropriate, indicating compliance with European standards.

Q5: Can I remove indicators from my modern motorbike if I don't like the look?

A5: No. If your motorbike was first used on or after 1 August 1986 and is a road-going vehicle, it is legally required to have working indicators if they were fitted as standard. Removing them would make your bike unroadworthy and it would fail its MOT.

Q6: Does the indicator warning light on the dashboard have to work?

A6: Yes, the warning light (or tell-tale) on the instrument panel that indicates when your indicators are flashing must also be working correctly for the MOT.

Conclusion

The legality of having indicators on a motorbike in the UK, and their impact on your MOT, boils down to a clear principle: if they're there, they must work. While certain older or specialist machines are exempt from the *requirement* to have indicators, the moment they are fitted (or were originally fitted and the switch remains), they become part of the mandatory safety check for the MOT.

For the vast majority of riders with modern bikes, indicators are a non-negotiable safety feature that must be maintained in perfect working order. Don't let faulty indicators lead to an MOT failure or, more importantly, compromise your safety on the road. A few moments spent checking and fixing your indicators can save you time, money, and potentially prevent an accident. Always prioritise clear communication of your intentions to other road users.
