The answer is to do with centripetal force. A higher mass required a higher centripetal force.

Explanation:

The equation for centripetal force is given by:

#F=(mv^2)/r#

Where:
F is the centripetal force
m is the mass
v is the speed
r is the distance from the centre of the circle.

We can consider a truck going around a bend as circular motion. If it is staying on circular motion, then there is a centripetal force.

From the equation, if v and r are constant:

#F=v^2/rm#
#F=km# where k is a constant
#Fpropm#

So as m increases, F increases.
A larger mass (lorry has a load) will require a greater centripetal force to keep it on its path. This will make it harder to drive the lorry.
