What type of measuring tools should be used at a crash scene?

When it comes to measuring tools used at a crash scene, tape measures and wheel tape are considered essential for accurately documenting the positions of vehicles, road markings, and other relevant features. These tools offer a practical and straightforward method for obtaining measurements that can be easily read and verified on-site.

Tape measures provide flexibility and precision in measuring distances between points, while wheel tape is particularly useful for longer distances, allowing investigators to quickly gather measurements without the need to lay a tape measure along the ground.

Other types of measuring tools, such as digital measuring devices and laser tools, can also be effective, but they may require specialized training or may be less practical in certain outdoor environments or conditions typical of crash scenes. String and compass are not standard measurement tools for crash investigations, as they would not provide the precision needed for documenting crash specifics like vehicle positioning and distances involved.

Overall, the use of tape measures and wheel tape ensures reliability and accuracy in documenting the scene, which is vital for subsequent analysis and reporting.
