just to add today it was pouring rain on my way to work and there were numerous spots (on 133 from shawsheen to the IRS building skabone will know) the road gets huge puddles. i noticed other cars ahead of me splashing through them and i slowed down, put in the clutch in someinstances, and swerved a little around them. just like skabones said just use caution when you drive and that should keep you safe 99% of the time.
