Fire crews from Calne and Royal Wotton Bassett had to cut out a person trapped in a car after a three vehicle smash in Hilmarton on Monday.
The air ambulance also landed to take the casualty to hospital.
But the accident has sparked fresh calls for a speed limit reduction at the junction near the A32102 to Compton Bassett.
Debbie Hughes-Morris posted: "I hope all concerned were ok. But it really is a dangerous junction.
"I've been indicating right to turn off the 3102, and had someone overtake me! It needs something, as there are far too many accidents at this junction."
