Fallen leaves may be colourful, but when combined with heavier autumn rainfall, they can catch out an unwary driver. Slippery leaves pose a significant traction problem. As they fall, they tend to accumulate near the gutter, then get soaked and stick together, effectively blocking drains and preventing water running away. So a combination of mushed up leaves and water quickly builds to create a possible skid area.
Watch out for leafy avenues where you may corner and be unaware that one or more wheels are sliding across the mulch at the same time. Darker autumn mornings and early evenings also make it harder to spot this sodden hazard. Best advice: treat leaves with caution and be ready to slow down, you need to be certain what it is you are driving on.
