Merging and lane changes: how to reduce blind-spot surprises

Most drivers underestimate the risk hiding just outside their view. A split-second lane change can turn routine driving into a near miss. Reducing blind-spot surprises is about awareness, positioning, and using the right tools.

Why this matters

Blind spots are where most collisions start. Even experienced drivers can miss a vehicle, motorbike, or cyclist, especially when merging or changing lanes. Minimising surprises keeps you, your passengers, and other road users safer.

Step-by-step method

  1. Adjust your mirrors properly – Side mirrors should show a sliver of your own car, plus as much of the lanes beside you as possible. Avoid the “classic” mirror angles that leave big blind spots.
  2. Check over your shoulder – A quick glance into your shoulder blind spot is faster than you think and confirms what mirrors can’t.
  3. Signal early – Give other drivers time to react. A late indicator often causes confusion and tension on the road.
  4. Scan traffic ahead and behind – Use your mirrors frequently, not just when you’re about to change lanes. Spot potential gaps early.
  5. Use technology where available – Dashcams with lane-change alerts or blind-spot detection can highlight risks before you move.
  6. Move smoothly and predictably – Jerky lane changes increase the chance of a collision. Commit once you start.
  7. Adjust speed to the flow – Matching traffic speeds reduces the need for sudden lane changes and gives you time to spot hazards.

Lane-change safety checklist

  • Mirrors aligned to minimise blind spots
  • Shoulder glance completed before every lane change
  • Indicator on at least three seconds before moving
  • Traffic ahead and behind scanned
  • Dashcam or alert systems active
  • Smooth, controlled steering
  • Speed matched to surrounding vehicles

Common mistakes

  • Relying solely on mirrors
  • Signalling too late or not at all
  • Checking blind spots only occasionally
  • Overestimating gaps between vehicles
  • Sudden or jerky lane changes

Questions to ask a cleaning provider

  1. Do you offer a full interior and exterior car clean before installing dashcams?
  2. Can you clean camera lenses without risking damage?
  3. How often do you update your cleaning equipment for safety?
  4. Do you use products that won’t leave residues on glass or screens?
  5. Can you accommodate quick clean-and-install sessions for busy schedules?
  6. Are your staff trained to handle delicate electronics and cables?

Quick wrap-up

Blind-spot awareness isn’t just a skill—it’s a habit. Adjust mirrors, scan thoroughly, and use technology to support safe lane changes. Staying alert reduces surprises and keeps every drive calmer and safer. Consider adding dashcam tools to your routine for that extra layer of protection.

Night driving safety: glare, fatigue, and visibility tricks

The road can feel completely different once the sun sets. Shadows deepen, headlights glare, and your eyes can tire faster than you realise. Small mistakes at night can turn into big risks in a matter of seconds. Even experienced drivers can underestimate how much night conditions affect reaction times. Glare, fatigue, and limited visibility are behind a large portion of avoidable accidents. Paying attention to them makes every trip safer. Step-by-step approach to safer night driving Adjust your headlights – Make sure they’re properly aligned. Too high or low and you’ll either blind others or reduce your own visibility. Keep your windscreen clean – Dirt and streaks amplify glare. A quick wipe inside and out before night trips can make a huge difference. Reduce dashboard brightness – Dim interior lights to avoid eye strain. Your eyes adjust faster to road conditions without competing light sources. Take regular breaks – Fatigue hits fa...

Road rage prevention: the “don’t win the argument” mindset

You can be right and still lose. On the road, “winning” an argument often means escalating it. A horn blast turns into tailgating. A hand gesture turns into brake-checking. Suddenly you’re not driving — you’re competing. The safest drivers understand one thing: don’t win the argument.   Why this matters Road rage is rarely about traffic. It’s about ego, stress and split-second reactions. When you choose to disengage instead of retaliate, you lower the risk of crashes, damage, and situations that spiral fast. Your goal isn’t to prove a point. It’s to get home safely.   The step-by-step method: how to practise the “don’t win” mindset 1. Decide before you start the engine Tell yourself this simple rule: No matter what happens, I will not escalate it. Make the decision before emotion gets involved. Pre-commitment works.   2. Expect mistakes from others Someone will cut you off. Someone will sit in the right lane. Someone will merge badly. If you...
