There are subtle differences between the terms slip, trip, and fall. A slip happens when you lose your footing. A trip occurs when an object or uneven surface makes you stumble. Falls often result from a slip or trip, and they happen when you lose control and move downward, landing on the ground.
Legally, the difference between a slip-and-fall accident and a trip-and-fall accident can be relevant. Slips and falls tend to involve injuries sustained from falling backward. Trips and falls often involve falling forwards. The types of injuries you sustain affect the compensation you can recover.
Further, proving negligence after a trip and fall might be different than proving negligence after a slip and fall. Every negligence case is unique, and different evidence will be required to prove fault.
