Why “Perfect” Summer Weather Can Increase the Risk of Road Traffic Accidents in NI

When the sun finally appears in Northern Ireland, many of us jump at the chance to get out and about, whether that’s a day trip to the North Coast, a drive through the Mournes, or simply enjoying clearer roads.

Most drivers naturally feel safer in dry, sunny conditions than during winter ice or heavy rain. However, summer driving in Northern Ireland comes with its own hidden risks and these can catch out even the most cautious motorists.

At JMK Solicitors, we’ve helped thousands of people recover after road traffic accidents across Northern Ireland. Over the years, we’ve seen clear seasonal patterns, and summer brings specific hazards that often go unnoticed.

Before heading out on your next summer journey, here are three key risks every NI driver should be aware of.

  1. The Hidden Hazards of Summer Allergies and Hay Fever

High pollen counts are common across Northern Ireland during late spring and summer. While hay fever is often dismissed as a minor nuisance, it can pose a genuine safety risk when driving.

Consider this:
If you are travelling at 60mph and sneeze, your vehicle can travel up to 50 feet with your eyes closed. In that brief moment, a car ahead could brake suddenly, or a cyclist or pedestrian could move into your path — with devastating consequences.

Medication Matters

Many over‑the‑counter antihistamines can also cause:

  • Drowsiness
  • Slower reaction times
  • Reduced concentration

Legally, driving while impaired by medication, even non‑prescription medication, is treated just as seriously as any other form of impaired driving. Always check that your hay fever treatment is clearly marked as non‑drowsy before getting behind the wheel.

  1. The “Greasy Road” Effect After Dry Weather

We’ve all experienced that first heavy shower after a week of rare NI sunshine. While the rain feels refreshing, it creates a treacherous surface on the roads.

During dry spells, oil, rubber, and dust build up on the tarmac. When the rain finally hits, it doesn’t wash this away immediately; instead, it mixes with the grime to create a thin, greasy film. This makes the road surface incredibly slick, much like “black ice” in the winter.

If you find yourself driving in the rain after a dry patch, remember that your tyres won’t have the same grip they usually do, reduce your speed, increase braking distance, and assume less grip than normal.

  1. Sun Glare: When Clear Skies Reduce Visibility

Low sun during early morning or evening drives can be more than an inconvenience; it can be completely blinding.

Sun glare is a frequent factor in rear‑end collisions and junction accidents, yet many drivers underestimate its impact.

It’s important to note: “The sun was in my eyes” is not considered a valid excuse if a collision occurs.

Drivers are legally expected to adapt to driving conditions, which may include:

  • Slowing significantly
  • Increasing following distance
  • Pulling over safely if visibility is compromised

A clean windscreen is also essential. Dust, smears, and residue intensify glare, effectively “whitening out” your view of the road. 

How to Stay Safe on Northern Ireland’s Roads This Summer

Summer driving should be enjoyable, but it requires a different type of awareness. By:

  • Managing hay fever symptoms responsibly
  • Adjusting your driving after dry spells
  • Taking sun glare seriously

you can reduce your risk of being involved in a road traffic accident and help keep yourself, your passengers, and other road users safe.
