The collision, reported shortly after 3:15 p.m., sent debris flying across the shop floor and left two pedestrians and the driver requiring hospital treatment. Emergency crews arrived within six minutes, treating an eight-year-old girl and a 39-year-old man for non-life-threatening injuries before transferring them to University Hospital of Wales in Cardiff.

Key Points

  • ✅ 76-year-old woman behind the wheel at time of crash
  • ⚡ Car struck shop interior, causing structural damage
  • 💡 No life-threatening injuries reported by South Wales Police

South Wales Police confirmed they had launched a formal investigation to determine the cause, including whether medical factors or vehicle failure played a role. CCTV footage from the service station’s exterior cameras captured the moment the grey Ford Focus mounted the kerb and burst through the glass façade, sending shopping baskets airborne and shattering display units.

💡 Pro Tip

Always check your mirrors before leaving a parking bay—especially on approach ramps where visibility can be limited and traffic speeds are higher.

Witnesses described the scene as chaotic, with one motorist, 42-year-old Lee Morgan from Pontprennau, saying he saw the car “swerve suddenly” before impact. “I heard a loud crunch, then glass everywhere. People inside were screaming,” he told local radio. Paramedics treated the injured on scene before ambulance crews arrived en masse.

Structural engineers assessed the damage to the shop, estimating repairs could exceed £25,000. A Moto spokesperson said the company was cooperating fully with authorities and had arranged alternative refreshment points for stranded drivers.
