What is a blind spot in motorcycles?

Every vehicle on the road, including motorcycles, has blind spots – areas that are difficult or impossible for the driver to see. On a motorcycle, the blind spot zone is particularly dangerous due to the lack of protective bodywork and the exposure of the rider.

The primary blind spot on a motorcycle is directly behind the rider and extends out a few car lengths. Riders cannot see this area by turning their head and looking behind them. They have to fully rotate their upper body to get a glimpse of vehicles or objects in this zone, which means things can easily be missed or noticed too late.

The side blind spots on a motorcycle are also significant. With a car, you have windows and pillars that can obstruct the view, but on a bike there’s nothing blocking the view, except the rider’s own helmet. The width of the rider and the motorcycle handlebars means that vehicles or objects more than a couple of feet away from the rear corners of the bike are outside the rider’s peripheral vision.

Explaining the blind spot zone (BSZ) in motorcycles

A group of researchers identified the blind spot zone (BSZ) for motorcycles in a 2019 study.

The BSZ for motorcycles can lead to dangerous situations and accidents. There are a few reasons for this to happen:

Limited peripheral vision

Motorcycle riders have a much more limited field of view than car drivers, due to there being nothing framing their vision. They can’t glance over their shoulder quickly to spot vehicles in adjacent lanes, and their peripheral vision cuts off close to their sides.

Reliance on mirrors

Motorcycle riders are heavily dependent on their mirrors to monitor surrounding traffic, but mirrors have blind spots and don’t give a comprehensive view of what’s around the bike. By the time a vehicle is visible in the mirror, it may be too late for the rider to react.

Visibility challenges

Whether due to nighttime riding, dirty headlights, or clothes/helmets that obscure the rider, other drivers may struggle to see the motorcycle, especially when it’s in their own blind spot zones. And if the rider can’t easily see the vehicle that can’t see them, a dangerous situation arises.

The key things motorcycle riders and car drivers can do are:

With everyone proactively taking steps to address limited vision and visibility, we can hopefully reduce motorcycle accidents stemming from blind spot zones.

How do I avoid a blind spot in a motorbike’s rear mirror?

In most cases, the blind spot issue arises because of the mirror’s height mis-adjustment or a problem with its mounting on the handlebar. Let’s discuss the best practices for avoiding this problem.

Adjust the mirrors properly

If you can see your shoulders in the mirrors, they’re not positioned correctly. You need to adjust them so you can see as much of the road behind you as possible without looking over your shoulders.

It will allow you to see what’s happening in the lane next to you and keep an eye on vehicles trying to overtake your bike.

Check the mirror’s mounting height

The most common cause of a blind spot is the motorcycle’s mirrors being mounted too high up on the handlebars. When you’re riding with the mirrors in the highest position, you can’t see the area behind the bike—and that’s where most accidents happen. The good news is that you can avoid this problem by mounting the mirrors a little lower on the handlebar.

Some riders like to have the mirrors mounted as far forward on the handlebar as possible, while others prefer to keep them mounted closer to the rider. It’s a matter of personal preference and comfort, so experimentation is the best way to find what works best for you.

Don’t get fixated on what’s behind you

It may seem counterintuitive, but you can’t get fixated on what’s back there for your safety. You shouldn’t spend too much time looking in your mirrors because it can cause a momentary lapse in concentration. As a result, you may find it harder to properly judge what’s happening around you.

The point of keeping an eye on the road and other traffic around you is that it helps reduce the risk of a collision by ensuring you’re aware of everything happening around your motorcycle.

Don’t rely on your mirrors too much

The blind spot is the area behind and to either side of your bike that you can’t see clearly in your mirrors. It is essential to know where the blind spots are so that you can look over your shoulder at these areas, but there will always be a small space that you cannot see – no matter how good your mirrors are.

You need to use head checks and mirror checks to ensure nothing has sneaked up on you. Use your instinct and diving expertise to make sure you aren’t going to hit something or someone when changing lanes.

Best Products for Motorcycle Blind Spot Detection

If you are too worried about blind spots while riding your bike, we suggest using any of these two products.


KiWAV Motorcycle Blind Spot Detection System


  • Warns of vehicles in blind spots
  • Increases awareness
  • Can be installed on most motorcycles within an hour


  • Radar sensors detect vehicles approaching or in blind spots
  • increases the rider’s awareness of surrounding traffic and road conditions
  • Easy to install


  • Expensive
  • Limited range

As a motorcycle rider, I’m always concerned about vehicles in my blind spots – those areas on either side of the bike that are impossible to see by glancing over my shoulder or looking in my mirrors. The KiWAV Blind Spot Detection system is a brilliant solution to this problem and could be a lifesaver for riders.

The system uses radar sensors mounted near the license plate to detect vehicles approaching or in your blind spots. When it senses a vehicle entering the 30-foot range of your blind spot, an LED indicator near your mirror will light up to alert you.

This gives you crucial seconds to react and avoid a dangerous situation.

However, while 30 feet of range covers typical blind spots, very wide vehicles or those moving at high speeds could be within a rider’s blind spot beyond 30 feet, so the system’s range limitations would need to be kept in mind.

The indicators are designed to attach securely near your mirror mounts and the system draws power from your bike’s battery, so no charging is required.

Installation seems straightforward, taking under an hour for most bikes, so you could have it up and running right away. To me, the potential risks of a blind spot encounter far outweigh the minimal time and cost required to equip your motorcycle with blind spot detection. I would feel considerably more at ease riding with this system monitoring the road around me and alerting me to hazards I can’t see.

However, the system does add an additional cost to purchasing/operating a motorcycle. The upfront and installation costs would need to be considered in the purchasing decision.

If you want cutting-edge motorcycle safety technology and peace of mind on the road, the KiWAV Blind Spot Detection system is worth a serious look.

FAQs about Motorbike’s Rear-View Mirror Blind Spot

What causes blind spot in a motorbike’s rearview mirror?

The rearview mirror’s design causes a blind spot directly behind the bike where the mirror cannot see. The mirror has a limited field of view due to its shape and position.

Is the blind spot dangerous while riding?

Yes, the blind spot poses a safety hazard while riding. Vehicles can enter the blind spot unnoticed, putting bikers at risk of rear-end collisions. Bikers must constantly check their mirrors and turn their heads to look behind them.

How can I reduce the blind spot while riding?

You can reduce the blind spot by installing extended rearview mirrors to widen your field of view. Riding techniques like frequent mirror checking, head turning, and shoulder checks can also help you detect vehicles in the blind spot area.

Do blind spot cameras or monitors help?

Blind spot cameras and rearview monitors can be very helpful by eliminating the blind spot. They give motorcyclists an unobstructed view of the entire area behind the bike. However, they are an added cost and require proper installation.

What should I look for when buying new motorcycle mirrors?

Consider convex or aspherical mirrors that reduce blind spots significantly. Open design with large reflective surface provides good visibility. Durable materials and adjustability are important. LED turn signal capability is a useful feature. Check mirror vibration at high speeds.
