- I will - Adjust speed of mixer drum to reflect the slump of the load (stationary for slumps between 20 and 50mm unless on straight road sections).
- I will - Always wear your seatbelt, just in case you are involved in an overturn incident – it could save your life.
- I will not - Drive too fast going through bends
- I will not - Drive too fast on roundabouts or corners
- I will not - Hit or ride up kerbs
- I will not - Make sudden or harsh steering inputs
- I will not - Brake suddenly or harshly
- I will not - Ignore the camber of the road in relation to stability.
To reduce the risk of overturn:
SAFE SPEED - Always adopt a cautious speed, and go slow when approaching, entering, driving through or exiting a bend, roundabout or corner.
- An increase in speed around a corner as little as 3 miles per hour can increase the chance of an overturn by as much as 20%
SAFE LOAD - When transporting ‘sticky’ concrete, with a slump of 20-50mm, avoid rotating the drum during travel
