Penalties and point deductions for some ordinary vehicles outside the highway are as follows: Speeding within 10% of the prescribed speed limit: No penalty for now. Speeding more than 10% but less than 20% of the prescribed speed limit: A fine of 50 yuan and 3 points deducted. Speeding more than 20% but less than 30% of the prescribed speed limit: A fine of 50 yuan and 6 points deducted.
