Peripheral Neuropathy and Driving: How to Foster Patient Independence and Safety

Peripheral neuropathy is a medical condition that affects the peripheral nervous system, which is responsible for transmitting signals between the central nervous system (the brain and spinal cord) and the rest of the body. This condition can cause a wide range of symptoms, including numbness, tingling, weakness, and pain, typically in the hands, feet, and legs. In some cases, these symptoms can be severe enough to interfere with daily activities, and driving is one of the most significant challenges that individuals with peripheral neuropathy may face.

For many people, driving is essential to maintaining independence and accessing work, social engagements, healthcare, and other vital services. However, peripheral neuropathy can impair a person’s ability to operate a vehicle safely. Keep reading for what your patients need to know about peripheral neuropathy and driving, the potential risks involved, and strategies for improving safety on the road for individuals affected by this condition.

Understanding Peripheral Neuropathy

Peripheral neuropathy is not a single disease. Instead, it’s a group of disorders that affect the peripheral nerves. The peripheral nervous system includes motor, sensory, and autonomic nerves. When these nerves are damaged, it can lead to a variety of symptoms that vary depending on the type of nerves affected:

• Sensory nerves: These carry signals from the skin and muscles to the brain. Damage to sensory nerves can lead to numbness, tingling, or loss of sensation, especially in the feet and hands.
• Motor nerves: These control the muscles and movements of the body. Damage to motor nerves can cause weakness, muscle atrophy, and difficulty with coordination and balance.
• Autonomic nerves: These regulate involuntary functions like heart rate, digestion, and blood pressure. Damage to autonomic nerves can cause dizziness, lightheadedness, or problems with regulating blood pressure and body temperature.

The causes of peripheral neuropathy are diverse. They range from diabetes (the most common cause), to alcohol abuse, infections, autoimmune diseases, inherited disorders, and exposure to toxins. For people with peripheral neuropathy, the symptoms may be constant or fluctuate over time, and the severity can range from mild to debilitating.

​How Peripheral Neuropathy Affects Driving Ability

Driving a vehicle requires coordination, quick reflexes, and the ability to make rapid decisions. Individuals with peripheral neuropathy may experience impairments that compromise these critical skills. Keep reading for some common ways peripheral neuropathy impacts driving.

1. Reduced Sensory Input
The most common sensory symptoms of peripheral neuropathy are numbness, tingling, and a loss of sensation, particularly in the feet and hands. These sensations can significantly reduce a driver’s ability to feel the pedals and perform precise movements. For instance:

• Foot pedal sensitivity: Drivers may struggle to feel the brake, accelerator, and clutch pedals properly, increasing the risk of over- or under-reaction when accelerating or stopping the vehicle.
• Hand control: Loss of sensation in the hands can impair the ability to grip the steering wheel or operate other controls, such as turn signals, windshield wipers, or gear shifts.

These deficits can lead to slower reaction times and more difficulty controlling the vehicle, particularly in emergency situations where split-second decisions are necessary.

2. Motor Weakness and Poor Coordination
Motor symptoms of peripheral neuropathy include weakness and muscle atrophy, particularly in the legs and feet. This can result in difficulty lifting the foot to press the pedals or maintaining the strength required for long drives. The loss of muscle strength may lead to difficulty in maintaining control of the vehicle, especially when maneuvering in tight spaces or making sudden directional changes. Coordination problems can also contribute to poor steering control.

Furthermore, weakened muscles in the legs can lead to fatigue more quickly, which may increase the risk of drowsiness or inability to stay alert while driving.

3. Balance and Postural Instability
Some individuals with peripheral neuropathy may experience problems with balance, especially when standing or walking. This can translate into difficulties with maintaining posture in the car, particularly in the event of sudden braking or sharp turns. While this issue may be less relevant in city driving, it can become critical on highways or during high-speed operation.

Moreover, if neuropathy affects the autonomic nervous system, it can cause dizziness or lightheadedness, making it dangerous to drive without warning.

4. Cognitive Impairments
Although less common, peripheral neuropathy may also come with cognitive changes, especially when the condition is caused by conditions like diabetes or when it affects the autonomic nervous system. These cognitive impairments can affect attention, memory, and decision-making—crucial components of safe driving.

Drivers with cognitive difficulties may become easily distracted, have difficulty making quick decisions in response to traffic signals or hazards, or even forget key safety practices like using turn signals or checking blind spots.

The Risks of Driving with Peripheral Neuropathy

The risks associated with driving and neuropathy are significant. Driving requires a combination of physical dexterity, quick reflexes, and mental focus. Individuals with peripheral neuropathy may be at a higher risk of:

• Reduced reaction time: Impaired sensation or motor function may delay a driver’s ability to respond to changes in traffic conditions, including pedestrians, traffic signals, or other vehicles.
• Increased likelihood of accidents: Difficulty controlling the vehicle, especially in unexpected situations, can increase the likelihood of collisions, side-swipes, or other accidents.
• Increased fatigue: Those with neuropathy may tire more quickly, leading to lapses in concentration and a higher risk of drowsy driving.
• Impaired decision-making: Numbness or cognitive changes can affect a driver’s ability to assess risk properly and make timely decisions, which may contribute to dangerous driving behavior.​

Driving with peripheral neuropathy can also result in legal consequences if an accident occurs. Many jurisdictions require drivers to report medical conditions that may impair their driving abilities. Failing to do so can result in fines, insurance claims, or even the suspension of a driver’s license if it is deemed that an individual poses a risk to themselves or others on the road.

Assessing Fitness to Drive

For individuals with peripheral neuropathy, it is essential to assess whether they are fit to drive. While the effects of neuropathy vary greatly from person to person, there are certain criteria and evaluations that can help determine whether it’s safe for someone to be behind the wheel.

1. Medical Evaluation
A healthcare provider, typically a neurologist or physician familiar with the patient’s medical history, can assess the severity of the condition and its impact on driving. This may include:

• Testing reflexes, strength, and sensation in the hands and feet
• Assessing cognitive and coordination functions
• Evaluating the patient’s ability to react quickly to simulated driving situations or physical tasks

In some cases, the doctor may recommend seeing a driving rehabilitation specialist, who can evaluate the individual’s ability to drive safely based on a more detailed assessment of motor skills, sensory function, and reaction times.

2. Road Tests
Some people with peripheral neuropathy may be able to safely drive with modifications to their vehicles. A road test can help determine whether the individual can drive in a controlled environment, such as a driving course or simulation. It is important that these tests consider the person’s physical capabilities as well as their mental and emotional capacity for driving.

3. Vehicle Modifications
In some cases, individuals with peripheral neuropathy may be able to drive safely with modifications to their vehicle. These may include:

• Hand controls: For individuals with difficulty using foot pedals, hand-operated controls can provide an alternative method for braking and accelerating.
• Custom seats or steering devices: Modifying the car’s interior to improve comfort and control may help enhance safety.
• Sensory enhancements: Adding devices that provide sensory feedback, like vibrating pedals or steering wheels, can help individuals with sensory loss regain driving perception and awareness.​

Coping Strategies for Safe Driving with Peripheral Neuropathy

If a person with peripheral neuropathy is still able to drive safely, there are several strategies to reduce risk and increase confidence behind the wheel. They include:

• Taking frequent breaks: Avoid long trips that can lead to fatigue, numbness, or discomfort. Rest stops can help maintain focus and energy levels.
• Limiting driving during challenging conditions: Avoid driving at night or in poor weather conditions when visibility or control is more difficult.
• Using adaptive technologies: Depending on the severity of neuropathy, adaptive devices such as hand controls, special grips, or modified seats can help increase safety and comfort.
• Focusing on physical therapy and strengthening exercises: Regular physical therapy may help maintain muscle strength and coordination, improving the ability to control the vehicle.​

Peripheral Neuropathy and Driving

Driving with peripheral neuropathy presents a range of challenges, but many individuals can still maintain their independence and safely navigate the roads with the right precautions and evaluations. The key is to assess one’s abilities and limitations honestly, to seek medical advice, and to consider alternative options such as vehicle modifications or professional driving assessments. 

With proper management, people with peripheral neuropathy can continue to enjoy the freedom of driving while minimizing the risks to themselves and others. Safety is always the top priority, and we offer multiple resources to help individuals make informed decisions about their driving abilities.
