Negligence: Evidence of Custom and Usage

activein force · 1995-01-01 – presentas-observed

Evidence has been received as to the (practice in the community) (custom in the trade

or work operation) (practice in the industry) with respect to (e.g., the use of 2 x 4's for

rafters) (installations of 3/8" plywood for subflooring) (standing on running board to guide

truck backing into shale pit). You should consider this evidence in determining whether

(defendant) acted with ordinary care. This evidence of practice is not conclusive as to what

meets the required standard for ordinary care or reasonable safety. What is generally done by

persons engaged in a similar activity has some bearing on what an ordinarily prudent person

would do under the same or like circumstances. Custom, however, cannot overcome the

requirement of reasonable safety and ordinary care. A practice which is obviously

unreasonable and dangerous cannot excuse a person from responsibility for carelessness. On

the other hand, a custom or practice which has a good safety record under similar conditions

could aid you in determining whether (defendant) was negligent.
