Summer is around the corner and with road trips, festivals and opportunities to explore the great outdoors, it’s a time of excitement. But with warmer weather comes hay fever season.
The worst hay fever symptoms tend to appear when it’s warm, humid and windy as this is when pollen count is at its highest. These symptoms can last for weeks or months and can affect your driving, potentially leading to substantial fines and penalties.
Safe driving requires good reactions and concentration. Hay fever symptoms can affect both of these skills and potentially make you feel drowsy. It’s important you read the information on your hay fever medication before driving, as they can vary in strength.
Try to take non-drowsy medication if you can and check with a doctor for any potential side effects before driving. Remember if your medication states ‘Do not operate heavy machinery’, this applies to cars.
You may struggle to drive in a straight line when you need to sneeze. According to The AA [1], if you sneeze while driving at 70mph, you’ll end up driving blind for 70 yards. This could be classed as ‘losing control of the car’, an offence with the following penalties:
To stay safe on the road, it could be worth considering adding a driver to your car using temporary car insurance. Available from one hour to 28 days, you can get them to give you a lift so you can sneeze without fear – and enjoy the peace of mind that comes with knowing your no claims bonus won’t be affected.
The Road Traffic Act 1988 prohibits driving under the influence of drugs that impair your driving ability. This includes decreased concentration and fatigue – both side effects of hay fever medication.
UK laws around drug driving [3] don’t distinguish between illicit drugs, over the counter and prescribed medication. If you’re found guilty of drug driving due to losing control of your vehicle, you could face the following penalties:
The conviction will appear on your licence for 11 years, which could increase your annual insurance premium.
Although it’s tempting, you should avoid driving when you’re unwell as you can be a danger to yourself and other road users. If you’re experiencing severe symptoms such as blurred vision, persistent dizziness, or extreme fatigue, it’s best not to drive.
Consider alternative transportation or wait until your symptoms improve. Even mild illnesses can have a negative effect on your driving.
If you do feel well enough to drive, despite your hay fever symptoms, it may be worth stocking up your car with the following:
You could also wear sunglasses (but not when it’s dark) to help keep pollen out of your eyes. If hay fever symptoms come on suddenly while you’re driving, slow down and pull over as soon as you get to a safe space.
You can be fined up to £1,000 if you do not tell the DVLA about a medical condition that affects your driving. While hay fever is not one of the conditions you have to report, it is still worth bearing in mind.
According to The Natasha Allergy Research Foundation [4], an estimated 16 million people suffer from hay fever in Britain. That’s one in four people and the number tends to rise year on year. Below are some of the symptoms:
The Met Office [5] states that tree pollen occurs first, typically from late March to mid-May, with grass pollen lasting from mid-May through July. Weed pollen can also be released at any time but the season typically covers the end of June through to September.
The NHS advises the following to help deal with hay fever:
While temporary car insurance allows someone else to drive, there are other alternatives to get where you need to go. You could grab a lift with someone in their car, get some fresh air and exercise by walking to your destination if it is nearby (if you feel comfortable enough with your symptoms) or use public transport.
The most important thing is to keep you and other road users safe.
