Some drivers have admitted that they had either laughed at someone soaked at the roadside, or had even intentionally drenched a pedestrian.
According to a survey carried out by the webuyanycar company, of the 2,000 drivers questioned, 16% have deliberately splashed water from a puddle over a pedestrian.
Nearly two-fifth of respondents said they have laughed when they saw someone soaked at the roadside. More than half (55%) took extra efforts to avoid getting people wet while 26% said they had soaked someone by accident.
Out of those who splashed, 12% stopped to say sorry. However, 17% did nothing and 16% admitted laughing.
Under the 1988 Road Traffic Act, motorists can be taken to court for selfish or aggressive behaviour while driving. However, the survey found that only 44% of motorists are aware of this.
Convicted drivers may also have to face an increase in their car insurance premiums.
A spokesman for webuyanycar.com said: "There seems to be a clear split on people's sense of humour and while some people may find this amusing, driving through puddles is not only inconsiderate but can also be dangerous."
He added: "When conditions are bad, it's important that we all act safely."
