Explanation:

- Option 1: Temper

- "Temper" is usually used to describe moderating or controlling something. It doesn’t fit the context of rules.

- Option 2: Trifle

- "Trifle" means to treat something as unimportant or without seriousness. It implies playing lightly, which can be inappropriate with driving rules.

- Option 3: Reckon

- "Reckon" is to estimate or calculate. While it involves consideration, it doesn't fit well in the sentence about how one should handle rules.

- Option 4: Tamper

- "Tamper" means to interfere, especially in a harmful way. It's suitable here, as altering driving rules can lead to unsafe conditions.
